Hi. I am trying to learn to how to define the materials of a 3D model on FENICSx platform, but with a property of spatially varying elastic modulus. I have created the material file .inp by Abaqus (every element of the model has been defined by its own different material paramters), But I don’t know…

Consider the following: import dolfinx.io.gmshio import meshio from mpi4py import MPI def create_mesh(mesh, cell_type, prune_z=False): cells = mesh.get_cells_type(cell_type) points = mesh.points[:,:2] if prune_z else mesh.points out_mesh = meshio.Mesh(points=points, cells={cell_type: …
