Hi all, Attached is the patch for changing the subdomain id to a typedef'd unsigned int from unsigned char. It fits my needs well and have not had problems dealing with 1000's of materials now. The typedef is defined on top of Elem.h.
Do have a look at the patch and if everything looks good (conventions and definition placement), do commit this. One more question though. It occurred to me that while doing this, in parallel, if you partition according to subdomain_id's it will lead to bad partitioning in my case. This is because I could sometimes have 'almost' random distribution of materials and since I am now maintaining material number with subdomain_id, I worry whether this will come back to bite me later. Do you see this to be a problem ? Vijay PS: My original libmesh sources have quite a few changes that do not exist in libmesh code repository and I had to weed out changes that you will not be interested here. So if anything seems out of place, feel free to remove it.
