ANSYS Workbench中CFX流固剖析时,流体固体之间的面怎样耦合

前面的疑问是可以的,CFX外面的耦合都是单向耦合,即一个物理场对另一个物理场的作用,也就是CFX跟结构离开计算的,所以不牵扯资料的种类。

ansys双向流固耦算计算的结果哪些可以删

力和力矩、静止和速度。

1、力和力矩:ansys双向流固耦算计算力和力矩包含流体对结构的作使劲和力矩以及结构对流体的反作使劲和力矩,这些结果在剖析中不关键,选用删除它们。

2、静止和速度:ansys双向流固耦算计算静止和速度包含流体和结构的静止速度和减速度,只有要结构的位移和速度,能删除这些结果。

自己最近在学习经常使用ansys FSI方法求解流固耦合疑问,在一个例子中有FSI set up,而我自己操作时却没有

特意是能源学。

GUI远远不能满足需求。

这是ansys外面的外面。

可以好好钻研一下。
