Solver Problem. Zero pivot when processing D.O.F 11 of 49 nodes
(OP)
Hello,
I have a question regards a thermal-electric analysis. I am trying to model how the electric potential will behave in a conductive material. I apply electrical potential at the corners of a material then I had to use a subroutine to use the electrical conductivity interaction GAPELECTR. Though, my program gives me the following warining:
Solver Problem. Zero pivot when processing D.O.F 11 of 49 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_11_1_1_2_1
Any suggestions on how to fix this? Also, the nodes that are shown vary with different runs..... :S

For example, for steady state heat transfer the default boundary condition is zero flux, which means "insulated" b.c.. In this case (heat transfer), if you prescribe a certain flux for a portion of boundary and nothing else for any other boundary region, the analysis will abort with zero pivots messages.
