2 Separate Stranded Coils in Multi-Turn Coil Domain

Hi all,

I have 2 separate stranded coils to be modeled for transient behavior (Current Pulse input). Since these coils are not of regular shape (linear or Circular), i had to go with numeric coil type in multi-turn coil domain.
Now i want these coils to be connected in series but not geometrically but in physics calculations hence i had taken 2 multi-turn coil domains and gave 2 separate inputs by electric circuit coupling. In 3D Multi-Coil domain calculations of "numeric type", it is necessary to add "Coil Current Calculation" step before going for transient solution to let the solver perform eigenvalue analysis hence gets the current direction.

Confusion here is :

Should i add 2 different "Coil Current Calculation" steps before transient study step ?
because if i do that it gives an error saying, "multiple threads not allowed" and also i can't work only with one "Coil Current Calculation" step because each multi-turn coil domain has a unique coil name, which is to be mentioned in "Coil Current Calculation" step.

I will be really very thankful if anybody could help me in this regard.

Thanks in advance.

Hello Mohit,

If you define the two coils separately and give them unique names, then I think you should add the two Coil Current Calculation Step before the Solver to compute the inputs for the model.

The exmaple in the following link will be very helpful

Regards and all the best

Hello Mohit

Did Wanjiku's response was helpfull for you?, I mean did it worked for you to put two current calculation steps and then solve for the magnetic vector potential?

Thanks in advance.

hi john
this e core example in two windings but my problem is one more coils add this transformer how these extra winding are connected in transformer.
plz help me ............john!
