Thanks for your reply! What if I have a smoothly varying properties, i.e. The properties are generally differently between neighboring elements. Can I use subdomain_ids to do that?
Could you please list some packages that can generate Exodus meshes? I only found that CUBIT can do this, but it is not free to use. Or if there is a documentation about Exodus file format. That will be even better. Besides, how xda supports subdomain? I have not found the information in the following document: http://libmesh.sourceforge.net/xda_format/xda_format.pdf Thanks, Mengda 2009/6/2 Derek Gaston <[email protected]> > And if all you want to do is assign different properties to different sets > of elements I highly recommend setting subdomain_ids on elements and then > just using those to infer what material properties should be used on each > element. > > If you build your meshes with something that outputs Exodus meshes... you > can create element "Blocks" that are assigned subdomain_ids... which will > automatically get read in and assigned when you read the mesh.
