How to import aerodynamic force from fluent simulation to ANSYS mechanical stress analysis tools

      I have designed the outer mold line of a drone and have put it through ANSYS Fluent to check its lift, drag, and pressure distribution. I am going to design the internal structure for the drone and I need a way to verify my design. Is there a tool in ANSYS that can allow me to see the force path and stress distribution of my aircraft skeleton using aerodynamic forces results I obtained through the fluent simulation?

      Hello,

      For this, you have to set up a fluid-structure interaction simulation using system coupling. For detailed demonstration, please go through the following links:

    Hi, what I have in fluent is this
    And My internal structure is this:
    I am trying to analyze the force and stress my internal structure would have to endure in the steady state using the data I have generated in Fluent, not transient state though.

    Hello,

    For this, you should have 'Fluent' and 'Static Structural' analysis systems in the workbench environment. After completing the fluent simulation, couple the 'Solution' tab of the Fluent to the 'Setup' tab of the Static Structural. During setting up the structural simulation, you have to import the loads from fluent.
    For detailed step-by-step tutorial, there are several videos available on YouTube (Hint: Try these keywords 'One-way Ansys Fluid Structure Interaction')

    Hello,

    Additionally, you can also perform one-way FSI using only Fluent (and not the Static Structural analysis systems). This is referred to as 'Intrinsic FSI'.
    Please refer the link for more details: Chapter 24: Modeling One-Way Fluid-Structure Interaction (FSI) Within Fluent (ansys.com)

    I hope this blog will be of help.
