Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix. Initial conditions solve failed to converge.

Hello,

I want to simulate a capacitor using The Polynomial Current-Controlled Voltage Source (PCCVS) but this error could be generate.

Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix. Initial conditions solve failed to converge.

Would you please help me.

This model is structurally singular because some variables are missing from the final set of equations. Double check if the equations and assumptions used to build this model. The current through Controlled Voltage Source1 does not appear in any equation.
