I have recieved this error when i was trying to import a 2D axisymmetric CAD model into the modelling window.
When I checked the model and noticed that im getting error message while transferring the model from geometry to simulation because model is not appropriately placed for 2D analysis. For axi-symmetric analysis we need to place the model such that:
-------------------------------------------------
The axis of symmetry must coincide with the global y-axis. The geometry has to lie on the positive x-axis of the x-y plane
-------------------------------------------------
