Fluent<->ANSYS Mechanical 双向流固耦合算例

hupo8522

Method:
Two-way FSI - data traversed between Fluent and Mechanical with the help of "System Coupling" - a new feature in ANSYS release 14.0.

Application package version:
ANSYS 14.0

Problem description:
It is a kinda quasi-2D model - there's only one layer of cell in the depth direction as u'r viewing. And NONE of the geometric dimension was strictly defined.
A container sinks in a flow field consisted of two phases of fluid and, the flow field is quite simple though.
Plz refers to the pic below:



General steps:
1. Structure side:
In Mechanical, "Fluid Structure Interface" and the Gravity were defined as the loads; The constraints forbid any deformation or motion beyond the plane u'r viewing (namely XZ plane). The "Material properties" was as default (Structural Steel).

2. Fluent side:
VOF was used in Fluent so as to define two phases of fluid. Initially, the two phase interface of the outer fluid was unbalanced in order to generate a small oscillation. The inner fluid was defined to make sure the container would sink. For the mesh deformation, only "smoothing" was activated.

3. System coupling side:
Double click the "Setup" under "System Coupling":


Define the coupling analysis time duration and time step size:


Define which two boundary regions should be encounted for data mapping and traversing:


Fluent VOF Result at t=1.215s:

fluent也能做双向吗？

这个例子对我来说很重要，请问最后动态的应力应变如何实现的？

楼主，在你的这个算例中，container（结构部分）是如何施加约束的，还是说完全自由的呢？

完全自由的
