Hei,

I am trying to assess and gain a general understanding of the modeling capability. I have created a toy model with two straight conductors, the magnetic field force of which I can theoretically calculate. I use this theoretical value as a goodness metric for the value provided by the model. Below is an image of the model along with descriptions of the parameters.

The formula for the theoretical value of force.

The model parameter values are provided below.

The simulated force results are provided for six different conductor cross-sections (0.001, 0.01, 0.1, 0.2, 0.3, and 0.4).

I believe that the cases with 0.001 and 0.01 are not pathological, and I wonder why the program fails to calculate correctly in those instances (assuming that the green cases are calculated correctly). I am trying to gain an overall understanding of the software’s capabilities and how I can address the situation when error messages occur.

Is it possible to configure the modeling software so that the cases with 0.001 and 0.01 come sufficiently close to the theoretical result (the correct result)?

Hi Kimmo,

In your last image, in concrete in the image column. I can see that you have warnings for the 0.001 and 0.01.

Warning: Major Mesh Repair -> Here you can try to use mesh operations to improve the mesh and/or try to test using the Classic mesh

Warning: Adaptive passes did not converge -> This is a clear message. You need to increase the number of passes. If the simulation does not converge then it is normal you are not getting accurate results. Please be sure your simulations converge.

I hope this helps.

Thank you for your response.

I recommend that you create tutorial videos addressing various warnings and error notifications, along with their potential fixes.
