[讨论]CFX5.7计算是出现的问题

+--------------------------------------------------------------------+
| ****** Notice ****** |
| Newtons method failed to converge in 100 iterations. This |
| occured while computing the following variable: |
| |
| Variable Name : Temperature |
| Location Name : liutiyu |
| Mesh location : VERTICES |
| Mesh entity : |
| Last 3 Changes : 1.34525E+00 1.34525E+00 1.34525E+00 |
| 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. |

Q: " I am getting finmes errors and the linear solver is failing. " <BR>A: Linear solver errors (or failures) such as this are usually caused by 'unphysical' boundary or initial conditions, especially if they occur on the first loop. We suggest that you check through your boundary conditions for any errors and consider using 'Automatic with Value' for the initial conditions. Sensible values can then be used to start the simulation, or ideally CEL expressions that approximate the expected solution field.
