All COMSOL® software products undergo stability improvements that are introduced as updates. The following list contains the most important improvements in COMSOL® version 6.0 update 2 (including those of update 0 and update 1).

COMSOL Multiphysics®

  • Fixed a potential security vulnerability by updating Apache Log4j to version 2.17.1. See Knowledge Base article here.0
  • Remapped the Gaia color table to use a logarithmic color distribution (rather than linear).1
  • Fixed a refresh issue in search results arising when multiple COMSOL Multiphysics® instances connect and save to the same local database.1
  • Added support for triple-clicking with the mouse in editable table cells in order to select all content (Windows®).1
  • Progress information now appears when saving models to a Model Manager database.1
  • Saving from the Recovery Files window for models using an add-in now works as expected.1
  • Fixed an issue where the manual residual-order setting for mesh adaptation could work improperly for solutions with several field components.1
  • Reduced the number of recovery files for long parametric sweeps in some cases.1
  • Fixed loading of old models with material switches.1
  • Added src2dst_mph and dst2src_mph to the Physics Builder. They are special multiphysics versions of src2dst and dst2src defined by contact pairs.1
  • Fixed a problem that made reconnecting to an app from another computer sometimes fail.1
  • Improved performance for the Apple silicon (M1) version of COMSOL Multiphysics®.2
  • Improved performance for circint(), ballint() and similar operators.2
  • Fixed searching in built-in and user-defined material libraries, which now ignores whitespace. For example, searching for BSL7 will find both Ohara S-BSL 7 Glass and Ohara BSL7Y Glass in the Optical material library.2
  • Fixed a problem where the ribbon tooltips for some multiphysics couplings had missing information in the Help window.2
  • Corrected the mapping of selections in transformed imported mesh.2
  • Corrected results of geometric measurements in components where there are meshes that define their own geometric model.2
  • Fixed an issue that sometimes caused the wrong geometric object to be measured when mixing imported mesh and geometry in the same component.2
  • Improved functionality when combining geometry and mesh that define their own geometrical models in the same component.2
  • Improved placement of node points that is now more robust for curved faces defined by a linear mesh.2
  • Fixed an issue whereby reduced-order models failed to properly account for direct dependencies of the eval operator and nonlinear outputs on frequency or time if the defining expression was not freq or t, respectively.2
  • Fixed the default zoom to selection behavior for reporting selection images so that it can now be overridden by choosing a locked view for the View setting.2
  • Fixed the numbering properties of a user-specified Microsoft® Word® template file so that they are now used when generating reports in a Microsoft® Word® format.2
  • Fixed an unexpected error that could occur when generating reports from templates.2
  • Fixed a bug in the Spatial FFT dataset that caused a crash.2
  • Fixed an issue where interpolation functions defined by a results table could sometimes give the wrong value when evaluated after opening a file, but before computing or updating the solution.2
  • Added an option for using the AMD® Optimizing CPU Libraries (AOCL), which are now available in addition to the previously available options for using the Intel® Math Kernel Library (MKL) and the standard BLAS library for AMD® processors with the ZEN architecture. To use AOCL, start COMSOL® with the command-line option -blas aocl.2
  • Stability improvements.0,1,2

Model Manager

  • A demo database for the Model Manager can now be automatically downloaded and opened using the Download Demo Database for Model Manager action in the Help menu.2 On the Windows® operating system, this menu is available as a submenu in the File menu.
  • The MODELMANAGER license feature is now included when borrowing the COMSOL Multiphysics® license.2
  • COMSOL Multiphysics® now provides a notification when the path of a new local Model Manager database seems to be on a cloud drive, which is not currently supported. See the Knowledge Base entry 1295for more information.2
  • Additional formats are supported when importing CAD files stored in a Model Manager database into a geometry: Parasolid®, ACIS® (SAT), STEP, IGES, and AutoCAD® (DXF™/DWG™).2

Model Manager Server

  • COMSOL Multiphysics® can now connect to a Model Manager server with CPU-locked licenses (CPU) and named single-user licenses (NSL) in addition to floating network licenses (FNL).2
  • The Model Manager server now includes a web-based asset management system that COMSOL Multiphysics® users can use to link models and simulation results to various documents, presentations, project notes, slides, and other supplementary files and metadata. Using the asset management system is also a simple way of sharing such files and metadata with people in your organization that may not have access to the COMSOL Multiphysics® — all while keeping everything in the same database storing the models.2
  • Setting up Transport Layer Security (HTTPS), external authentication with AD/LDAP, and reverse proxy-based authentication is now supported directly within the Model Manager server system administration web interface.2
  • Setting up user management and access control for a server database from the Model Manager server database administration web interface is now possible.2
  • Fixed a potential security vulnerability by updating Apache Log4j to version 2.17.1. See Knowledge Base article here.0
  • Ensured that managed Apache Solr servers only listen on the localhost interface on Linux® and macOS.1
  • Stability improvements.0,1
  • Security improvements.1

COMSOL Compiler™

  • Fixed a licensing problem with compiling apps in version 6.0. See Knowledge Base article here.0

Application Builder

  • Fixed a memory leak in Test Application.1
  • Fixed an issue with the number format precision for data display form objects used in add-ins.1
  • Fixed an issue with using TLS for the SMTP server connection when sending emails.2

AC/DC Module

  • Performance improvement: significant improvement in evaluating coil parameters in Frequency Domain Perturbation studies.1
  • A new Circuit Extractor add-in is available under the AC/DC Module in the Add-in Libraries window for generating electric circuits from solved physics.2

Acoustics Module

  • Fixed an issue in the Port and Lumped Port conditions in the Pressure Acoustics interface when the conditions are used together with symmetries (the Symmetry condition). Cases where the port is used together with symmetries are now handled correctly when the setup is meaningful.2

CAD Import Module

  • Support for importing SOLIDWORKS® 2022 files.1

CFD Module

  • Fixed variable definitions in Flow Continuity pair conditions.1
  • Fixed an issue where any model created in version 6.0 that uses a porous medium with an activated k-epsilon turbulence model or any other transport-equation RANS-based turbulence model could have produced incorrect results. With this update, it is no longer possible to use this physics combination, and only the algebraic turbulence models (Algebraic yPlus and L-VEL) are supported in combination with a porous medium. An implementation of transport-equation RANS-based turbulence models in porous media is planned for a future release.2

Chemical Reaction Engineering Module

  • The Dispersion subnode is now available in the Porous Catalyst and Packed Bed nodes.1
  • An error now appears when the heat capacity (Cp), to be used in a Reacting Flow multiphysics coupling, is zero.2

Heat Transfer Module

  • Added a warning to inform that Moisture Flow and Reacting Flow multiphysics couplings do not support the LES turbulence model.1
  • Heat Source, Initial Values, and Out-of-Plane features are now applicable on Porous Medium using Local thermal nonequilibrium or Packed bed types. Heat Flux, Lumped System Connector, Surface-to-Ambient, Boundary Heat Source, and Deposited Beam Power features are now applicable on adjacent boundaries of Porous Medium using Local thermal nonequilibrium or Packed bed Porous medium types. When these features are applied on Local thermal nonequilibrium, Packed bed domains, or adjacent boundaries, the effective temperature is used in the feature equations. To apply the fluid or solid temperatures of the porous medium instead, use the subfeatures of the Fluid, Porous Matrix, or Pellets nodes.1
  • Fixed an issue with the initial temperature for the Lumped Thermal System Connector.1
  • Corrected Pair Boundary Heat Source contributions when the heat source is defined from a feature input.1
  • Fixed the Mikik elastic correlation option in the Pair Thermal Contact feature.1
  • Fixed some issues defining the volume and surface factor in shells due to curvature or 2D axisymmetric modeling.1
  • Fixed an issue with the view factor storage in Surface-to-Surface Radiation to avoid unnecessary recomputations.2
  • Enabled the Thin Layer feature on pairs.2
  • Corrected the Solid velocity for cases where Moving Mesh and Deformed Geometry are combined.2
  • The Pipe Connection coupling, which requires a license for the Pipe Flow Module, can now be used for a coupling to fluid flow using a license for the Heat Transfer Module.2

LiveLink™ for Simulink®

  • Fixed an issue for particle tracing used in a cosimulation when using a model method to continue running a solver sequence without a model update.2

Microfluidics Module

  • Added a missing initial value for Temperature in the Slip Flow interface.1

Optimization Module

  • Fixed an issue with semianisotropic scaling in the transformation features for shape optimization.2

Porous Media Flow Module

  • Fixed an issue with the poroelasticity coupling when opening models created with versions prior to 6.0.1
  • The equation for Unsaturated Porous Medium when using the From density and porosity storage model was modified, which eliminates the undefined variable error for the storage variable.1

Ray Optics Module

  • Fixed an issue whereby domain accumulation in ray optics gave an incorrect result for the first mesh element reached by a ray leaving an unmeshed domain.2

RF Module

  • Improved mesh adaptation on subsets of domains, in particular for models with perfectly matched layers, by excluding residual contributions from domains in which adaptation is not performed. Consequently, the error estimate in such domains will be zero.1

Subsurface Flow Module

  • Fixed an issue with the poroelasticity coupling when opening models created with versions prior to 6.0.1
  • Improved the equation display for Darcy's Law including gravitational forces.1
