Ansys Employee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?

Ansys Employee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.在Conditions输入con-outlet-temp-avg。
c. 从Report Definition下拉菜单选择之前创建的出口平均压力outlet-temp-avg。
d. 在Stop Criterion栏输入 1e-5。
e. 在Ignore Iterations Before栏输入 40 。
f. 在Use Iterations栏输入 50 。
g. 勾选 Print.
h. 设置Every Iteration 为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 ”
