    Problems with mixed mesh: plates/beams

    Thank you for your replies. @ GBor: Your solution is the best for sure; but I am operating on a complex unstructured meh, where the beams (more than 1000) are positioned on a complex patter: to add a spider I should remodel the whole structure to position support nodes in a proper way; or I...

    Problems with mixed mesh: plates/beams

    Hi the structure is 3D, I only sketched an idea here. Imagine two disks meshed with plates which are kept together by those beams. The only dof which is free is RZ for plates, that is RX for beams; for this reason I expected that K6ROT would be enough. Beam torsion is NOT a load path, so I'm...

    Problems with mixed mesh: plates/beams

    Hi all I'm having a problem with a mixed mesh composed by beams and plates for a static analysis. The system is well constrained but I receive errors typical of meshes with mechanisms, i.e. high pivot ratios. The structure has a (qualitative) shape...

    Importing cosmosworks meshes of into nastran

    I thank you but we should be able to export with Cosmos itself. I just would like to know if I didn't setup Cosmos export or contact options in the proper way or it's bug in the software. I mean: if an exporter to Nastran is provided, I expect that produces the right gap elements. Has anyone of...

    Importing cosmosworks meshes of into nastran

    HI all I am trying to import a assembly meshed with Cosmosworks 2005 inside Femap for setting up the analysis with Nastran. I don't want to import the geometry into Femap because it would take a longer time to prepare a good mesh. In this assembly there are some surfaces on contact (pin/hole...
