Trying to create an electrical circuit

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:

I haven't asked this question but, THANK YOU VERY MUCH. You've just saved my life!

How dificult starting with Simulink is!
