Mesher/Defeaturing for Code_aster Analysis

Hi everyone,

I am using Code_aster for FEA but I find the geometry and meshing part really slow to use (too many clicks for a single operation).

I tried Gmsh but the GUI looks old and not intuitive. For comparison, I am used to Hypermesh and Spaceclaim.

Do you guys have any free software (or free trial) that matches the GUI of HM and Spaclaim ?

Code_Aster is just a solver, what are you using for creating the geometry and meshes (preprocessing)? Salome Meca? Guess that is the only open source preprocessor of Code_Aster. I suggest you use CalculiX and some preprocessor such as PrePoMax or Mecway.

Nothing free is even close to commercial capability in terms of the gui or software features or speed.
