Hi! When I draw a certain component (motor stator or rotor), especially when I want to duplicate my basic geometry, I always need to make sure that there are no overlapping nodes or segments in order to prevent MEX error. Are there any ways that could automatically merge overlapping nodes and segments?

Thank you very much again. I found my mistake why previously I had different flux linkages using xfemm and FEMM. Previously, instead of starting from -10 mm, my iteration for flux linkage calculation started from -9 mm (shifted by 1 mm due to previous loop for force calculation), therefore, it looked as it was shifted from FEMM results by a certain amount. Now results are close to each other. These flux linkages and inductances are still different when comparing xfemm and FEMM. In the code that you...

Thank you! I have run the code that you attached. Interestingly, after I ran this code, the results of the flux linkages of xfemm (and FEMM) became closer to the FEMM results which I had previously (almost identical). But my previous xfemm flux linkage results are still different, as if the flux linkages are shifted by some value. So I am still looking at that.

Yes, both FEMM and XFEMM files are attached.

Hi! I solved one problem first using FEMM and then using XFEMM Matlab functions. I compared the results of the flux linkages for these two cases, but there is a difference in results (plot attached). I could not understand why. The boundary conditions and maximum element areas are all identical in both cases. I also tried to increase the number of mesh elements in XFEMM, but there is still difference in the results. What could be done to make XFEMM results more accurate and close to FEMM results...

Hi! Is it somehow possible to view a mesh plot of the design using XFEMM in Matlab?
