我最近用cfx10计算球头激波诱导点火,结构很简单,但是mach都在3--5左右。计算很难收敛,残差跳动严重。而且有以下提示:
****** Notice ****** |
| Newtons method failed to converge in 100 iterations. This |
| occurred while computing the following variable: |
| |
| Variable Name : Total Temperature |
| Location Name : out |
| Mesh location : BELG7 |
| Mesh entity : IP |
| Last 3 Changes : 1.66743E+08 1.66743E+08 1.66743E+08 |
| 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.
有大家不吝赐教!小弟先谢了! |
