Imprecision due to resistance in parallel with a current source

Hi everyone.

I am trying to simulate the distribution of a very concrete current wave into a circuit with different paths. All these paths have influence ones in the others due to quite a lot of magnetic mutual couplings

.

I am comparing several softwares: Pscad, Microcap, LTSpice, and Matlab. And I am getting the biggest desviation and complication when ussing simulink.

When connecting a current source to an inductance in simulink, I am obliged to include a large parallel resistance, and it always takes a certain amount of current, wich affects the results. The other softwares are able to jump over this restriction, so all the current goes into the circuit without small looses through the resistance.

I am thinking about increasing the amplitude of the input current to compensate the current flow through the resistance... but I prefer to look for more accurate solution...

Some opinion, recomendation, orientation...?

Thanks in advance, David

Using Simscape instead of specialized power systems will solve this issue when it is realistic. The signal needs to be continuous since current through an inductor cannot change instantly.
