Hello, I would like to know if there is the possibility or any equivalence to ABAQUS UMAT(Abaqus users do programs with FORTRAN) in ANSYS Mechanical where I could enter my own program that has a particular mesh for the geometry, solving a particular problem with personalized stiffness matrix but only the solution is visualized with ANSYS Mechanical tools (displacement, deformation, etc.).

Is there any course recommandations or tutorial allowing me to program ANSYS Mechanical preprocessing and processing?

Thank you.
