WebJan 2, 2016 · Geometric nonlinear analysis of membranes by using finite element method is done. The finite element code is written in MATLAB. The theory documents in included which describes geometric nonlinear theory for membranes. The results are verified by COMSOL Multiphysics (FEM software). Cite As Amit Patil (2024). WebAs another rule of thumb, if you check "geometric nonlinearity" option on the study, you should probably solve for moving mesh as well (if you solve for anything in the air at all). It is similar to fluid-structure interaction. There is some forms, where you have e.g. an acoustic coupling between solid and air.
