I would like to import a geometry with different volumes of different materials. I created the CAD-Modell in Autodesk Inventor Fusion and exported as STEP (STL alternatively). I then meshed the STEP in NETGEN under Ubuntu and exported as Diffpack mesh. This I converted with dolfin-convert to dolfin-XML. With this combination I get a main XML of the structure: ... ... ... ... Also I get 9 files of naming ..._marker_1 which seem to host boundaries. Their structure is: ... I would like to import the mesh and access the two subdomains. I understand that mesh_value_collection is a class similar to mesh_function. I tried to create an instance of a mesh_value_collection from file by mesh = Mesh('test11.xml') ValueCollection1 = MeshValueCollection('int',mesh,'test11.xml',3) But it cannot read the MeshValueCollection tag that way. What is the most intelligent way to import subdomains from a mesh? Is there a better way of pre-processing? If MeshValueCollection is the way to go: Is it appropriate for differentiating subdomains and saving material properties? Or should it be used to create a Mesh_Function later on? Grateful for all kinds of help...
