Hi everyone,
I'm modelling coils using the Multi-Turn Coil Domain - I have a transmitter coil with an applied current and two receiver coils beside it. I have to find the induced voltage across the receiver coils. The model is 3D and I'm doing a frequency domain study.
Right now I need to import some CAD files from SolidWorks. The problem is that the geometry is too complex to form a union (I get "Internal geometry error"), so I formed an assembly instead. But for some reason the Multi-Turn Coil Domain doesn't seem to work any more. I've attached some files with a simplified geometry to test the form assembly operation.
The first problem is that I'm no longer able to select a reference edge for the coils. Originally I had a parametric curve which defined a circular edge midway through the coil (average location of the wires), but with the assembly if I try to select that edge it says "not applicable". See my first attached file. It seems that I'm only able to select edges that belong to the coil's cylinder.
So instead I decided to build the coils using a layered 2D circle and then extrude it, which created an edge where I want it (see my second attached file). Now I can select the reference edge, but when I ran the simulation the results made no sense - it says the coil voltage is several orders of magnitude smaller than it should be.
Does anyone have any idea what's going on? Have I missed something setting up the Multi-Turn Coil Domain for the assembly, or does the Multi-Turn Coil Domain need a union? Or from a different perspective, how can I get the Form Union to work with very complex geometry?
Thanks in advance,
Neil
