The operator DEFI_MATER_GC allows you to define the parameters of materials used for civil engineering studies.

The aim is to help the user define material parameters from more physical quantities.

In this command, we enter the physical properties (elastic coefficients, elastic limits, characteristic resistances,…), at the output we have a material concept, which can then be assigned to the various meshes with the affe_material command.

Produces a mater-like data structure.
