Issues of continuously transposed conductor (CTC) modelling

Please login with a confirmed email address before reporting spam

Dear COMSOL Community, I am using COMSOL for some time and this is the first time I have encountered a problem. So, this is my first post in this forum. I am trying to investigating frequency dependent inductance due non-uniform current distribution and skin/proximity effect in solid and continuously transposed conductor (CTC) at high frequency upto 3 MHz. For this purpose, I have developed very simple 3D circular coil models of solid condutor and CTC with 5 strands. (Previously, I have also worked with 2D axisemmetry models to observe the effect of frequency on inductance of the coil and everything worked).

And now I have simulated the 3D solid conductor coil model and it also works fine. But I have issues with the simulation of CTC coil model. I have tried to use different solvers but it is not working and solution does not converges. Can someone in the community help me in this regard? I have attached the model of simple 5-strand CTC.

Secondly, as if we increase the no. of strands in the coil the geomatry becomes complex to build mannually. So, Is there any tool or code in COMSOL to create the geomatry of CTC with many strands?

I would really appreciate your help in this regard.

Thank you, Mehran
