HI, MY QUESTION IS I HAVE TO DEFINE AN INLET AT THE LOCATION SPECIFIED IN THE SCREENSHOT ATTACHED.
CAN ANYONE HELP ME HOW TO DEFINE IT?
The easiest way is to split your stl file into 2 files: one that has only the inlet surface at the bottom of the loopseal and another one that has everything else. Then you can load the 2 files, apply the mass inlet to the bottom plane and no slip wall to the other file.
You can also achieve the same by selecting the stl faces with the selection shape, method and filtering based on the normal vector, but here I think it will be easier just to split the stl file from your CAD software.
