To do this, the boundary of the airfoil body must be defined in the dynamic mesh section in system coupling. To define the desired boundary in Fluent software, we should use dynamic mesh Because the meshing around solid boundaries changes over time due to the deformation of solids, and as a result, the mesh around these boundaries must be considered moving. Now it is necessary to define the walls or boundaries of the model that are affected by the FSI in the environment of Fluent and Transient Structural software. We also should establish a coupling between the geometry of each of these two software.

To do this, you must first define the model in each of the Fluent and Transient Structural software and then couple the process of solving them with this system coupling, and also considering that the geometry is the same in both fluid and solid design modes. To define two-way fluid-solid interaction, we should use system coupling in ANSYS Workbench software. We also use Remeshing, when the displacement of the borders is large relative to the size of the local cells to regenerate the destructive cells of the critical size limit. According to the smoothing method, the number of nodes does not change and only adjusts the mesh of an area by moving or deforming the borders. In the determination of dynamic mesh methods, smoothing and remeshing methods have been used. When using the FSI method, due to the change in the structure of the fluid flow mesh around the geometric model, it is necessary to define a Dynamic Mesh Because the Dynamic Mesh technique allows changing the mesh structure of the model in a time-dependent manner. Therefore, we use the FSI method in the ANSYS Workbench software environment. As a result, we can say that a two-way confrontation occurs between the fluid and the solid. Due to the fact that this airfoil is moving in the air with a considerable speed, the air flow collides with its body and exerts force on it.

In this simulation, a circular computational domain of вЂ‹вЂ‹airflow is designed So that an airfoil is located in this area. It will copy the tutorial project containing the geometry into your Workbench.The present problem simulates the airflow around an airfoil using the Fluid Solid Interaction ( FSI) method in ANSYS Fluent software.
