1. But

Assign materials to geometric areas of a mesh or model. There can be up to 26 materials on the same mesh (which is necessary for multi-fiber beams or polycrystalline materials), but it is only possible to use a single field of the field type field in the operators.

Define control variables (temperature, space, hydration, drying, corrosion,…) for numerical calculations.

Produces a data structure of type cham_master.
