brajh11 is on a distinguished road
hey all, after giving all boundary condition for gas combustion, i got following error during solver. Please help me to understand this error.

Anybody are experienced in this? any suggestion on this problem?


Parallel run: Received message from slave
-----------------------------------------
Slave partition : 3
Slave routine : NEWT_FIT
Master location : End of Continuity Loop
Message label : 009100013

| ****** Notice ****** |
| Newtons method failed to converge in 100 iterations. This |
| occurred while computing the following variable: |
| |
| Variable Name : Temperature |
| Location Name : Default Domain |
| Mesh location : VERTICES |
| Mesh entity : |
| Last 3 Changes : 1.64457E-01 1.64457E-01 1.64457E-01 |
| Tolerance : 1.0000E-02 |
| |
| The Newton iteration was either slowly converging or has stalled. |
| The solver will continue with the variable set as it was on the |
| final iteration. If this situation continues you might try |
| increasing the number of iterations allowed for Newtons method. |
| This can be changed by setting one of the parameters: |
| |
| Temperature : "Constitutive Relation Iteration Limit" |
| Pressure : "Newton Pressure Iteration Limit" |
| |
| for your mixture using the definition file editor. |
