Basic Installation

I am new to the SW (and FEA in general).

I have version featool-multiphysics-1.12.4

I installed it as a Matlab App using the FEATool Multiphysics.mlappinstall file.

When I start the app, I got the following warning.

Starting the FEATool Multiphysics GUI.
Loading resources can take a minute . . .
. . . . . Warning: Incompatible MEX files detected. Functionality such as the
MUMPS linear solver and fluid-structure interaction (FSI) solver
will not be available. Please change to a compatible and supported
operating system and/or MATLAB version if these features are required.
 
When I run the commend featool testt, it says FAILED with the following log file text.
Most of them finished OK, some of them failed with "Error running GUI script!"

Did I install it wrong?

The warnings indicate that the shared Matlab mex/libraries for certain solvers can't be loaded nor used due to system incompatibilities. Most likely you can use the most functionality anyway as most of the test suite seemed to pass.
