My geometry cotains two solids,so elements information in .dat file is divided into two parts(both are same material).I awnt to use PyMapdl reader to read all elements information from .dat file but it just read the first part elements information.How should I do?

No source file, test, or reproducible .dat file is identified in the issue. Start by obtaining a representative .dat file with two solids and tracing the PyMapdl_reader parsing entry point; done means element information from both sections is returned, with a regression test covering the case.
