I encountered the following errors at the "corner nodes" of my geometry while trying to compute.
My boundary conditions are correct.The model runs fine with heat equation off.But when I include heat transfer equation , I am getting the error shown below.Kindly post suggestions to help me.I tried making mesh finer ,filleting etc,but could not solve the problem.Mine is an axisymetric problem.
Undefined value found.
- Detail: Undefined value found in the equation residual vector.
There are 95225 degrees of freedom giving NaN/Inf in the vector for the variable mod1.T.
