In OpenFOAM, for each boundary patch, user has to input boundary condition for p and U (both) similar to ‘custom’ B.C on SimScale.
Coming back to SimScale platform, I would like to simulate fluid flow through an applicator with pressure Inlet and Pressure outlet (which is 0, atmospheric) conditions.
My questions are,
- When I select pressure outlet condition, I believe ‘zero gradient’ is applied for ‘U’ at outlet patch.
Which B.C. is indirectly applied for ‘U’ for ‘Inlet’ patch??
2)What is the significance of Gamma value in ‘pressure inlet’ B.C??
I would be grateful if someone could help me out. Thanks in advance.
