With these assumptions, the compressible energy equation is greatly simplified so that the resulting low-Machnumber equations are represented in tensorial notations as follows:
用STARCCM做船舶阻力分析,考虑升沉和纵倾,之前流域底部设置为速度入口,结果会收敛。考虑浅水效应即流域底部的影响时,我把底部的边界条件修改为壁面 结果不收敛 且提示如图警告-the mesh may have non-positive volume cells,请问前辈是壁面条件不能修改为壁面而是其他,还是修改为壁面后需要再修改其他的地方,谢谢
