Sorry for hijacking the topic. I am happy to create a new topic if deemed necessary. Please advise.
I recently changed jobs and on the new work PC (running ANSYS 2019 R3), I have encountered the same phenomenon. This was not occurring in my previous workplace's PC (running ANSYS 2019 as well). I don't recall encountering this issue previously; having used multiple different work PC for ANSYS and multiple versions.
Admittedly, I am currently dealing a lot more with surface models at this workplace instead of solids, hence, having to set up contacts a bit more diligently (nothing complicated; only selecting top/bottom shell face, turning on shell thickness effect, adding offset (no ramping) for frictionless contacts).
Whenever I add a new contact (example selecting 2 faces and adding a manual contact), the mesh requires remeshing. Here I was thinking, it might be because I am dealing with surface models. Could it be something to do with the default setup of mesh, etc.?
I can provide screenshots of the settings if required.
