In geotechnical engineering, effective stress updated from fluid flow module will be used to update strain(or deformation).

Actually, all the fundamental mechanisms of solid-liquid-gas interaction in soils are highly coupled with each other. How to define a highly-coupled nonlinear 1-D stress-strain relationship in Comsol? Should it be through other module such as PDE module or Moving Mesh(ALE) ?

Sincere thanks for your help!
