Simulation Running too slow

I am trying to do a simple power system simulation. I just need to view the rms value of current. But since, the simulation is running very slow at steps of 1e-8 seconds, I am only getting instantaneous value. How to just solve the circuit for steady state condition? Here is a picture https://lh4.googleusercontent.com/-tBjv-eZlM2I/Tk1auvIklLI/AAAAAAAAA80/YeXeE8z1q0A/s800/too_slow.JPG

Any particular reason using such a small step size? What is the frequency of the signal that you are simulating?

I don't have that Toolbox. I remember reading some posts here that the simulation step is variable step. I think you can go to menu Simulation->Configuration Parameters ...Solver to set up the maximum step size. Step size of 1e-8 seems to small. 1e-3 sounds more reasonable.

Okay. There might be some dynamics that require small step size. To find out, you can choose fixed step size and then try-and-error a few times, form 1e-4 to 1e-5, 1e-6, etc.
