flotran中,为什么某处温度会小于所有的环境温度?
本帖最后由 麦克斯韦 于 2009-9-9 10:18 编辑flotran流体分析,流速最小处温度最低,甚至低于初始和环境温度,流速继续增加甚至会便成负值,提示错误,计算终止?
*** ERROR *** CP = 27.125TIME= 10:13:14
Negative or zero temperatures may be avoided by either mesh refinement
or modified inertial relaxation especially if Petrov-Galerkin
formulation is used for the energy equation(FLDA,ENRG,SUPG,T).
*** ERROR *** CP = 27.188TIME= 10:13:23
Negative or zero temperature detected. This may be caused by a
diverging solution or by an incorrect temperature or property value.
A temperature offset may also be required. (TOFFST)
Node = 241. 网格加密后,问题更严重
1# 麦克斯韦 对温度水平对流项使用MSU方法,代替Petrov-Galerkin方法 很好很强大学习一下
