  I have given the boundary conditions similar to the one in Ansys help. But I am getting an error. I have attached the images of the solution information. Help me to solve this error.

  Which Ansys Tool are you using for this simulation?

  TOFFS is usually set by Mechanical as 273. You should confirm this in the ds.dat file. Otherwise a negative temperature might be caused by wild swings in the temperature of an unconverged solution. As a test you could try a very small current value. Have you compared your material properties to an example in the APDL Coupled-Field Analysis Guide?

  I used a current value of 1 ampere and the material properties I took from research paper. I don't know how to confirm using ds.dat file . Could you help me with that.
