Simscape Model - Issue when using Transformer

I am getting the following error command when running my simscape model:

• Initial conditions solve failed to converge.
• Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix.
• The model may not give enough information to make it possible to solve for values of some of its variables. Specific advice is given below. all components and nodal across variables involvedTie variable 'Ideal_Transformer.p1.v' (Voltage) to a definite value, for example by connecting an appropriate domain reference block. Dependency found among topology equations. Check for missing reference node.

Hi Krishna,

I assume that you are using a Current Source on side 1 of the Ideal Transformer block. The error message, “Check for missing reference node” suggests that the circuit is missing a reference block. Adding this block to the circuit on side 1 will fix the error:

Here is the fixed model for your reference:

I hope it helps!
