I am using poroelasticity module. I have a problem about the self-defined parameter and build in variables.
I defined shear modules,G, as a function of axial displacement, w (a build in variable), and w is also influenced by G. i.e, they are interacted with each other. But I find that the self defined function G hasn't been invoked by the module.
In other words, how to self define a function or variable which is correlated to build in variable in comsol. I find it doesn't work if I just type a function in the to-be-defined variable.
anyone can give me some suggestions?
