Thank you very much, onesupeng and Prof. Luo.
The negative density appeared when I implemented the immersed moving boundary method. In short, the result was good when the obstacle was motionless, while moving would cause negative density. The Ma=0.09333 and tau=0.502 are suitable since the former(motionless) ran correctly. Did it relate to a question of boundary conditons? Or ...?
Thanks in advance! |
