Hello MATLAB community, newbie here. I am trying to simulate a rectifier on Simscape but the simulation is extremely slow. You can check out the screenshot at http://i1302.photobucket.com/albums/ag127/renguoma/rectifier_simscape_zps57f15786.jpg
I have tried using ode23t solver with accelerator and while it did run faster, the output seems incorrect, as can be seen from the link below. http://i1302.photobucket.com/albums/ag127/renguoma/946efd9d-1bb2-4056-acc2-eedb8d7a9475_zps959bcf1e.jpg I expect the output to be DC and yet I see a sine wave. I have simulated the same circuit in SimPower and had no problems with it. Please help.

This is an effort to answer old unanswered questions on Matlab answers:
The signal is rectified, it's just that the capacitor is not charging and holding it's charge. It is likely the circuit parameters need to be changed such as a larger resistor. This could also explain the slow simulation time as the smaller the rc time constant, the slower the simulation will be.
