For my final year project, I am trying to reproduce thesis results to get familiar with the simulation procedure and to validate my method. I modeled the rotor blade and stator vane using BladeGen and after meshing, imported those to Ansys CFX. My working fluid is NOVAC 649. Since I couldn't get the RGP files, I manually added the material to the CFX setup. After that, I introduced the inlet total temperature and pressure and for the outlet, the static pressure is provided as the boundary condition. But after a few loops, 100%area of both the inlet and the outlet has been covered with the wall and the solution gives an error. When I try the open boundary condition, I cannot see any pressure, temperature variations in the results. Hence I tried introducing the mass flow rate for the outlet and ended up with different results. Can anyone help me with this problem?
