How can I apply a zero current density to a 2d conductor with out getting eddy currents in an
ANSYS 9.0 transient thermal-electric analysis?
You need to specify a very small non-zero values of JS (instead of exactly zero ). This activates the
"nonzero JS current density behavior" of PLANE13 which supersedes what happens when RSVX is non-zero. When
RSVX is non-zero and the VOLT DOF is NOT active, the element behaves as a "shorted conductor" (in 2D models,
a solid ring) which produces eddy currents unless you override this with |JS| > 0.
