Inaccuracy of inductance computation #3

Open pfuchs opened 3 years ago

pfuchs commented 3 years ago

The inductance computation included in the tool is a guideline at best, and not at all dependable or stable. It would make sense to either change the algorithm (internally use a magnetostatic solver on the line segments or something along those lines) or investigate the inaccuracies of the current algorithm using a commercial solver and some test cases to improve this feature.

Is it the reason causing large error (Error over 140mm DSV>50%) in X direction using default parameters? LargeError

pfuchs commented 2 years ago

No, the inductance calculation is done separate from the field/gradient computation, so they should not lead to any error there.
