I want to model a relatively simple 2D surcharge condition onto an existing soil layer, which I can do by hand...however, I need to show PRINCIPAL STRESSES in a 2D model for a specific geometry. Recommendations for a low-cost FEM software that has soil models and can produce principal stress plots would be GREATLY APPRECIATED! Platforms such as CRISP & PLAXIS are too expensive of an investment for this relatively simple problem.
