Hi,
When i performed in mesh for larger geometrical length, there was no error. When i reduced the scale via
, this error
Code: Select all
ERROR:: IterSolve: Failed convergence tolerances
appeared.
Solution :
I changed the
Code: Select all
Solver 1
...
Linear System Max Iterations = 350
...
End
to
Code: Select all
Solver 1
...
Linear System Max Iterations = 1000
...
End
Then there was no error.
Another Possibility,
Although, the error could be eliminated by changing
Code: Select all
Solver 1
...
Linear System Convergence Tolerance = 1.0e-8
..
End
to
Code: Select all
Solver 1
...
Linear System Convergence Tolerance = 1.0e-4
..
End
Doing this in this particular simulation gave some unrealistic temperature results.
However, this method needs to be implemented with reasonable assumption when "changing only number of linear system max iterations" don't cause the avoidance of the error.
I understood now the meaning of this quote

.
Inference:
Hence, the possible solutions are:
1. Increasing the number of linear system max iterations.
2. Decreasing the value of linear system convergence tolerance.
