BCTABL1 for MSC Nastran

Hi everyone. In HyperMesh 2019 it was possible to choose the contact pairs (BCONECT card) which should be used for BCTABL1 in contact browser. But in HyperMesh 2020 something changed in interface and I can't find this functionality. How to choose contact pairs (BCONECT) for contact table (BCTABL1) in HM2020 release for MSC Nastran solver?

    I looked into the Contact Browser help in HM2019 release and in HM2020 release for Nastran solver. There is same descriptions, nothing is change. It seems like a software bug. It's very strange, because can't create contact table in HM2020...<?xml version="1.0" encoding="UTF-8"?>BCTABL1.thumb.png.8335e1cb51935a7e78c187ee136ad1c9.png

    I encountered the same issue. I ended up having to define it manually in the BDF after exporting...Not an ideal way of doing it, but it works.

    Yes, this was a bug. It has been fixed in 2021.
