Hello, I have a 3-phase cable I am trying to add to an inverter (as shown in the figure below) and I keep getting the following errors.
I have assigned an external winding (for the conductors in green) in Maxwell 3D and named them as the load inductor in the Twin builder (L1, L2 and L3). I am using Magnetic transient solver, I have enabled the coupling between twin builder and maxwell, made the same solution setup for both the files for analysis.
Errors I get:
- Maxwell 3D:
1.a. Simulation completed with execution error on server
- Twin Builder:
2.a An external simulator couldn't be setup for simulation
2.b Simulation completed with execution error on server
I am using the following references:
- Page 11 in http://ansoft-maxwell.narod.ru/en/Maxwell_v16_L05_Transient_Solvers.pdf
- The resource mentioned in Researchgate: https://www.researchgate.net/profile/Sabah_Vs2/post/How_can_I_perform_Co-Simulation_of_PMSM_using_Ansys_Maxwell_and_Simplorer/attachment/5dfb04443843b0938396f96f/AS%3A837687686754305%401576731716118/download/Maxwell+-+Simplorer+Cosimulation+-+Copy.pdf
Technically, I know that the 3-phase cable is capacitive nature, but modeling it as an inductor does not seem right. Am I doing it right? Any references/ tutorials in the right direction would be greatly appreciated!

Change excitation in Maxwell from external to a user defined excitation, run the simulation in Maxwell and see if there is any error. Follow a similar procedure in simplorer, removed the linked component from Maxwell and change to inductors in simplorer. Run the simulation in simplorer, see if there is any error. nNovember 6, 2020 at 12:28 amarshiahSubscriber, Thank you for your reply. nI tried simulating both the models in Maxwell and twin builder independently and they work fine. Any help to debug the co-simulation would be greatly appreciated! Thanks! nNovember 12, 2020 at 4:59 pmicellb1Ansys EmployeeHi, ,nI don't see obvious error from the information you provided. It seems like a connection/link issue. You could try following: n1. Reconnect the Maxwell design to the simplorer circuit. 2. add a small series resistor to the voltage source. 3. The reference you used on Page 11 in http://ansoft-maxwell.narod.ru/en/Maxwell_v16_L05_Transient_Solvers.pdf is not about linking to simplorer but to external circuit in Maxwell. That could be another operation that messed things up. nNovember 12, 2020 at 5:16 pmarshiahSubscriberSure, I shall try that Thanks for your reply!nViewing 4 reply threads
