Hello,
I have a model in which I would like to create an injection of gas in the centre of a pseudo-2D bed. That is, similar to an internal tube but that releases some air. I would like to retain as much as possible the circularity of the injection, so I have decided not to go for a PS. I am trying to use two STL files, one with a cylindrical hole in the centre of the region for the bed with the internal and another STL that fills that hole and that acts as a BC with mass inflow conditions. However, this does not seem to work and I don’t see any gas injection.
Any ideas on how to perform this simulation or what I could be doing wrong?
Thanks!
