Hello everybody,
I am trying to build a model in COMSOL made by four different PDE to simulate heat and mass diffusion inside a porous material. I need to build the model myself to validate results from literature as well as modify some terms for other needs.
I have already defined the equations, however I do have a small difficult to understand how to integrate functions as coefficients.
In particular, I would need to define such function as show in image
I am not sure how to define the function itself, but also how to use as VARIABLE of the step function one of the PDE variables.
I hope you can help me out with this!
