Hello, I'm currently at a point where HyperMesh seems to run out of options, or I want to do more than HyperMesh was designed for. I'm experimenting with Nastran's glue contact surfaces, with attributes BSURF, BSURFS and BGSET. Now, I have already created funcionality in HyperMesh for BSURF(S) and BGSET, but now I want to create a custom connector to use this functionality in HyperMesh. I have a construction made out of several layers of shell or solid elements and I want to 'glue' all the intermediate surfaces/solids to eachother. Seeing from the functionality for, for example, bolts, HyperMesh is capable of realising connections with purely the connector location, the to be attached components/surfs/elems and a tolerance value. Of course, information of the type of connection is required as well, but many are preset. Now I'd like to create my own custom connector, allowing me to input the to be connected contactsurfs and a tolerance value, and let HyperMesh figure out which contactsurf should be connected to which other contactsurf. After that, it should all be formatted in the NASTRAN's BSURF(S) and BGSET. Now the latter can be arranged via a post processing script that you can add to the FECONFIG.cfg file. My question is, is the former (creating a custom connector) possible to users in HyperMesh, or is it solely purposed for Altair development? Thank you for your time and help. Jeffrey PS. Please see the attachment. I want to be able to select contactsurfs 1, 2, 3 and 4. The idea is that contactsurf 2 is connected to 1. Contactsurf 3 is connected to 2, etc. This functionality is already present in bolt creation, that's why I want to make use of the HyperMesh connectors rather than write a MATLAB script to do the same.
