help me solve this question, please

description:

The following two blocks cannot be connected in series:

Block 1: 'Controlled Current Source'

Block 2: '10 Ohms '

The first block, modeled as a current source, cannot be connected in series with the inductive element of the second block.

Add a high-value resistance in parallel with one of the two block.

You can also specify high-value resistive snubbers if the blocks have a snubber device.

i added a resistance in parallel with one of my block. questions following:

1. i dont know how to choose the value of resistance avoiding effects on simulation results;
2. adding a resistance may cause Algorithm divergence.

thanks
