La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
This example studies a portion of the vascular system of a young child. The aorta and its ramified blood vessels are embedded in biological tissue. The pressure from the moving fluid deforms the blood vessel. The complete analysis consists of two distinct but coupled procedures: a fluid ... Per saperne di più
A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you ... Per saperne di più
In this benchmark example, a semi-elliptical crack at the inner surface of a cylinder is studied. The inside of the cylinder and the crack faces are subjected to a pressure load. The J-integral is calculated along the crack front, and the stress intensity factor is then compared with the ... Per saperne di più
This tutorial model shows how to model a structure using both shell and solid elements, and how to create the transition between them. Results are compared between the shell solution and the full 3D solution, and the effects of the transition are highlighted. Per saperne di più
A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, one of the three material principal directions — the out-of- plane direction — has a higher yield stress than the other two. Hill’s orthotropic plasticity is ... Per saperne di più
This model calculates the eigenfrequencies and mode shapes of an unconstrained cylinder in axisymmetry. The model is taken from NAFEMS Free Vibration Benchmarks. The eigenfrequencies are compared with the values given in the benchmark report. Three different physics interfaces are ... Per saperne di più
In this example, a lumped model of a vehicle suspension system having 11 degrees of freedom is analyzed. The Mass, Spring, and Damper nodes of the Lumped Mechanical System interface are used to model the wheels, including suspension system as well as the seats with a passenger. The ...

Polymer hydrogels consist of a crosslinked network of long-chained polymers that has imbibed a large number of solvent molecules. Such materials are used in many biomedical applications, such as targeted drug delivery, tissue engineering, and stimuli-sensitive actuators. This benchmark ... Per saperne di più
This example shows a 2D plane stress model of a thin tapered cantilever. Different boundary and load scenarios are examined. It is demonstrated how to apply and how to evaluate different load and constraint groups. Resulting stresses are compared to NAFEMS benchmark values and they are ... Per saperne di più
This model shows how to perform a submodeling analysis in order to evaluate structural stress. Using a submodel helps to compute the results in a refined geometry detail while applying loads and constraints in the global model. Per saperne di più
