Copying to libmesh-users; this is getting into questions of general interest that I'd like a search engine to see.

That's the most scalable way to do things, and it's what I use, but if you have to do anything sophisticated then writing the code for it becomes harder. You can still construct a SerialMesh manually if you find the need though. > --enable-complex You don't want this on unless you're solving complex-valued problems. For various reasons (primarily the fact that we can only link to one PETSc at a time) complex-valued Number support mostly *replaces*, not just augments, real-valued Number support, and solving real-valued PDEs is more efficient with real-valued matrices. > --enable-tecplot --enable-curl --enable-blocked-storage --enable-gzstreams > > Still don't have gzstream Ah! It looks like we have gzstream in contrib, but it depends on finding libz libs and headers installed on your system. I've never used a system without libz-dev installed so I've never noticed. :-) > or hdf5 (not sure if that is needed).

VTK only if you need to output those files. TBB no; I believe if you don't have it then we fall back on openmp which may work better, if you do want to use threads or hybrid parallelism rather than just pure MPI. --- Roy ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
