Materials file

Create the materials file "cmas2d.mat". This file stores the physical properties of the material under study for the problem type. In this case, defining the density will be enough.
Enter the materials in the "cmas2d.mat" file using the following format:

MATERIAL: Name of the material (without spaces)
