The next preview of new features in TwinMesh 2018: we implemented a mesh interpolation method in User Fortran. So far, the time step size of the CFD simulation has to be set according to the desired revolution speed and the prescribed angle increment of the pre-generated meshes from TwinMesh. Now it is possible to set an arbitrary time step size, and the corresponding mesh is calculated with a spline interpolation between the pre-generated meshes at run-time.read more
Preview on new features in TwinMesh 2018: we have implemented non-reflective boundary conditions (NRBC) in ANSYS CFX via User Fortran in a stable and robust way so that they can be used for positive displacement compressors instead of the standard openings which are reflective (RBC). While RBC lead to standing waves, especially at pressure side with mass flow strongly pulsating and even flow reversal, NRBC allow pressure fluctuations from pressure port to travel to the outlet and leave there without any artificial reflections so that mass flow is more uniform and realistic.read more
