Hi,

I am making arc welding simulation using this interface. Should I only define the current in the Electric Current interface and needn't to define the current density in the Magnetic Fields cuz I see there is an Induction Current Density Component and Static Current Density Component which can maps them to the other interface.

And for the laminar flow, is it proper that I can change the Compressibility option which is set to incompressible from weakly compressible.

Thanks,

Wenli
