Hi guys, I am trying to draw a circuit like the one in the picture link. http://img513.imageshack.us/img513/1501/circuita.jpg
I drew up a circuit using simscape and simulink. And it is as follows. http://img28.imageshack.us/img28/8900/circuit2.jpg
However, the error keeps popping up: Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix. Initial conditions solve failed to converge. Dependency found among topology equations. Check for missing reference node.
I just started using matlab, and would really appreciate any help for this. Thanks in advance.

The error is clear... "Check for missing reference node" means that your circuit does not have a reference. Add this block to ground your circuit:
