Hi,
I'm not used to work with Abaqus on electrical issues.
I try to put a current of 0.5A on a specimen. Current enters the top side of the specimen with 0.5A and leaves at the bottom side with -0.5A. Is this setting correct to simulate a current of 0.5A trough the specimen?
The next question is how to query the electric potential from two different points(I want to simulate the crack size in the specimen). Do I just query the EPG of those points and calculate the difference? Is it given in Volt then?
