may i add some comment to the discussions,
user can manage by grouping trough compound part, an option to merge or separated mesh is available.
in case of large models in element and node, high performance computer is required and investing RAM capacity is highly recommended. speed of processor, number of cores/thread is a plus.
PrePoMax does not have feature in modeling a part, only by importing common 3D CAD file format. so, an external software to modeling is a must.
also, automatic tetrahedral element is supported only from imported part to be meshing. structured mesh is not, user need an external software with the capability to produced an UNV or INP formats. in this case, someone could chosen Salome CAD/CAE due to it’s completeness of feature…
right, it’s not yet supported. hopefully in the future PrePoMax can be capable to import of line based element and provide basic interface to defining cross section dimensions.
