Re: [Libmesh-users] an error I don't understand

I don't think I can get away without using MeshData. The reason I'm using
libmesh  is precisely that I have data on a given (huge) mesh that I am
using as input...

Without running in parallel then, do you think the problem is too large to
converge within a reasonable time frame?
