Hello, friends,
Now I use level set method to simulate the premixed flame. However, I encounter two problems as follows,
I am not sure whether the methods described above are right. But the problem is that the zero level set surface does not move a little!!!! Could anyone give me some suggestions? Many thanks. Every idea is appreciated! Best, Wen |

Now I figure it out that if I do not use the reinitialization step, the zero level set does can capture the flame front at the first times. However, the front will biased as the time proceeds.
When the initialization step is implemented into the level set process, the zero level set moves with a irregular routine. The reinitialization step code is as follows: Quote:
Thank you in advance! Best regards, Wen |
