Automation of COMSOL Multiphysics Parameter Studies using the MATLAB LiveLink

COMSOL Multiphysics is a Finite Element Methods (FEM) software package for the numerical solution of partial differential equations. The MATLAB LiveLink combines the powerful FEM abilities of COMSOL with the versatile programming environment of MATLAB. This tutorial shows how to utilize the LiveLink for the frequent application of a parameter study. The FE analysis is invoked for several parameters by a M-File and its results are post-processed in MATLAB. As demonstration example serves the verification model large deformation beam from the model library. It is modified such that its geometry is parameterized. It can then be solved and post-processed automatically for several parameter combinations by a M-File. This tutorial refers to versions: COMSOL 4.2a and MATLAB 2011b.
