Hi @Andrew Y,

I am unable to reproduce this issue on my end. If you are using Restricted Mode in Simscape, then this error with the callback is possible when trying to use the model, as stated here:

Could you please provide the exact reproduction steps along with the model being used?

Also, what do you mean by dragging the fuel cell blocks to workspace?
