Dear all, Hoping all is doing well with you. I'm asking for a module for calculationg the earth curent in a grid high voltage DC. Also the name of Multiphysics. Kindest Regards Samar

It would be the short circuit current of the battery bank. I'm not sure if manufacturers test for this and publish the results, but if they don't, the calculation I'd recommend for estimating it, would be open circuit voltage / internal resistance at maximum operating load. I wouldn't be surprised if it weren't common to test for this, as it certainly would ruin the battery and likely be dangerous to do a direct test.
