Hello, I am using VWT to access to the surface pressures on a model. These are then to be exported and applied to the model within HyperMesh via linear interpolation. I recently came to realise that if I move the model in VWT then the nodal pressure coordinates that I can then export to a .txt file are wrong. They do not align with the nodal coordinates of the model within HyperMesh, but refer to the region of space that they occupy in VWT. Thus, you must translate and rotate the model in HyperMesh first. This is justifiable and works for just one loading scenario. The problem I am having is that I wish to do a weighted compliance topology optimisation with multiple loading scenarios that require the angle of incidence of the flow to change. Therefore, if I rotate the model, the pressure files nodal coordinates will change and I will not be able to use the same hypermesh file (as it will have to be rotated accordingly too). So, is there a way to change the direction of the flow or rotate the windtunnel within VWT - so that my model can stay constrained in its geometrical space but the loading scenario can change? Thank you in advance.
