热源功率设定，在6000时，正常收敛，当为10000时，报错

尊敬的各位版主，高手： 在真空辐射的计算过程中，热源功率设定为6000W/m^3时，计算结果最高温度为1000K，收敛无问题。当继续增加功率至10000W/m^3时，计算报错，不知哪位高手给予解答下。谢谢。 |

俺得到的正解： One issue one can easily get with dissusion equations is that, in transient studies particularly, the gradients from the initial conditions are very steep, and the mesh being used is not compatible (too coarse in certain regions). If you are in stationary, what you can ry is to ramp up the power with a solver - contianuation tab - prametrical sweep case and increase the power in 5-10 steps, then each solver case is using the previous results as starting point, and often this allows you to reach your max flux values |
