Improvement: Support nastran file MPC entries #36

Closed kristsaet closed 1 month ago

kristsaet commented 1 month ago

As at least ANSYS is really happy to create meshes, using lots of MPC entities, it would be convenient that Fedem supported this way of creating a mesh.

Ok, I did not see that it already was an issue related to MPC..

Indeed, this was requested already in #7. It turns out we already support MPCs in the SESAM file reader (see the method FFlSesamReader::readLinearDependencies()), where they are converted into equivalent WAVMG elements (which again are representation of RBE3-Nastran elements). Therefore, #7 can be fixed by doing a similar implementation for the Nastran reader.

@kristsaet if you have a sample Nastran file with MPC-entries for testing, we may have this available relatively soon. It can be attached to issue #7 or sent by email to kmo@openfedem.org
