如何给Fluent添加判断收敛的条件?

      比如,我想让Fluent求解器满足如下条件时终止计算:当出口平均温度在50步内的变化量小于0.001%时计算终止。该如何实现呢?

      首先定义出口平均温度,选择Solution Reports Definitions New Surface Report Mass-Weighted Average...

      注:若监测多个出口变量,则重复上述方法创建即可。

       

      其次,创建基于出口平均温度outlet-temp-avg的收敛条件.

      Solution Reports Convergence...

      a. 点击Add按钮,

      b.Conditions输入con-outlet-temp-avg

      c. Report Definition下拉菜单选择之前创建的出口平均压力outlet-temp-avg

      d. Stop Criterion输入 1e-5

      e. Ignore Iterations Before栏输入 40

      f. Use Iterations栏输入 50

      g. 勾选 Print.

      h. 设置Every Iteration 5.

      i. 点击 OK 保存当前的收敛条件设定并关闭Convergence Conditions 对话框。

      对于多个出口监测,则按照上述方法增加多个收敛条件即可,并勾选勾选“All Conditions Are Met
