I am getting this error, "The following region in contact with another region has no material assigned to it: region11. ". I don’t know how to resolve it. There is no such region as region 11 in my CAD, closest thing would be flow region. How do I find region 11 and how to resolve this issue?

Any help will be greatly appreciated.

Green ticks show all the initial requirements have been fulfilled.

Hi nniloy,

I see that you are able to run a simulation do you were able to solve the issue yourself?

Self checking revealed material was not assigned to one part. However initially, green stick was present beside “Material” despite a part not having its material selected. Issue has been resolved and was able to run the simulation.
