Can Simulink sim powersystems simulate pure LC circuit with multiple grounds

Hi. I would like to find the transient response of a purely LC circuit with multiple grounds. The simulation seems to require that I enter resistance values in parallel with the source for the DC step response. I need to know the natural frequency of the system, and it has multiple ground points. An attempt is pictured.

I believe you’re right about including some resistance when using Specialized Power Systems. I believe that simulation should be possible using Simscape Electrical with Simscape technology.
