We never really conceived of it as a stable "standard", just something that could let our users save files without trashing data (p refinement levels, exotic FE types, whatever) that might not be supported in pre-existing standards. We add new data every couple years: nodeset/BC/subdomain names and element unique_id values in 0.9.2, node unique_id values in 0.9.6, edge and shellface BCs in 1.1.0, more complicated field width encoding in 0.9.2 and again in 1.3.0... and we don't even bother adding write options for old formats, just backwards compatible reads via version string. Honestly the easiest way to write a mesh converter would probably be to write a libMesh MeshInput subclass and use our meshtool app. If you need something standalone, I'm sorry but the only authoritative source on the format is src/mesh/xdr_io.C --- Roy _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
