Hi,

I am running a MATLAB simulation with PLECS Blockset. In my PLECS Blockset, there is a grid model embedded inside a subsystem. Using Signal inport and signal outport, i am feeding in and taking the signals from the system. I am getting this unusual error which doesn’t point to any port or terminal. I have attached the screenshots and simulation model to this question. Your response awaited.

Thanks

Shahbaz Hasan

Hi Hasan,

Would it be possible to attach the initialization commands file --“SAPF\_MPC\_capload\_parameter” so that I can try and simulate the circuit?

Hi Manu,

Thanks for the prompt response. I have attached the script you can run the script to update the workspace for initial commands.

Hi Shahbaz,

This could be a bug. I will get back with a definitive answer tomorrow.

Hi Shahbaz,

This is indeed a bug. The developers suggested the following workaround–  
“To fix the Circuit block, you need to copy the complete schematic into a fresh Circuit block (and then you need to also copy all simulation parameters).”

Hi Manu,

I will try this workaround and will get back to you with the status.
