求助,本人在做热流体固耦合时,最后一步静应力分析,solution出现红色闪电符号,报错显示An unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes.
图如下

前面计算合适着,最后一步出错,试过tools里面的调试,还是不行。
使用Reynolds stress model (RSM)进行计算的过程中,设置入口为速度入口,出口为压力出口。速度入口通过表达式的形式输入,设置入口速度函数为分段函数的形式,分段函数在分段点连续不可导。fluent计算过程中连续性方程中有对函数速度求导,但是在计算的过程中没有报错,请问这种速度入口边界函数设置合理吗?
While in geometry the word barycenter is a synonym for centroid, in astrophysics and astronomy, the barycenter is the center of mass of two or more bodies that orbit each other. In physics, the center of mass is the arithmetic mean of all points weighted by the local density or specific weight. If a physical object has uniform density, its center of mass is the same as the centroid of its shape.
