How to alter the .bdf to change contact settings from Glued to touching.

Hello, I have an assembly with 4 parts, and I need to swap 2 of the 3 contact settings from glued to touching with a friction coefficient of 0.05. Bodies 1, 2 , and 3 should be touching, while bodies 3 and 4 should be glued. I'm looking through the nastran reference guide, but interpreting the matrices within matrices is proving difficult.

Thanks for any help!

also, you will need to add the BCONPRP entry ID to the BCONECT field 4 or it won't be turned on.

BCONECT, ID, BCGPID, BCPPID

Your best approach is to do all this on a simple samplemodel, and if you have issues getting it to work, it is best to open a support case with MSC Technical Support... it is sometimes more difficult to communicate at a detailed level via the forum.
