I have a cylinder with the inlet face oriented in YZ direction. The length is along X direction. Say this cylinder is now rotated about Y direction 50 deg. I want to create an iso surface in the center plane along the length in the new axes. How to do it.

 

If the cylinder is in regular orientation, i can say create iso surface in constant z . Now since it is rotated how to do it? 

 

If the geometry has parts oriented in different directions, is there a way to create one iso-surface or plane to represent the entire geom to view the flow

Moving this to the “Result Visualisation” thread.

You can create a plane by prescribing 3 points. So a cross-section normal to the Z-axis of your original cylinder can be created by prescribing 3 points: (i) 0, 0, 0 (ii) 0, y, 0 (iii) x, 0, 0

Now if you rotate the cylinder along the Y-axis by 50deg, the 3 points required to create the mid-plane normal to the Z-axis would become: (i) 0, 0, 0 (ii) 0, y*cos(50), 0 (iii) x, 0, 0

Is this what you’re looking for?
