I have built my model in altair optistruct but i want to export it as nastran bdf file to do analysis in Nastran. However, I am not able to find contact surfaces and contact interfaces bulk data in bdf file. I dont know what's going on there.

    Make a test with Nastran profile? A very small model and export to BDF.
