Can I slice a fluid volume into multiple parts?

    • El_Manguangua

      I'm currently studying a two-way Fluid-Structure Interaction (FSI) between air and an aircraft wing, and while I managed to do some structured meshing with the wing by slicing its skin into multiple parts and hence reducing the number of elements, I haven't managed to do so with the fluid volume. I'm thinking of doing the same for the fluid volume, but I don't know if that could somehow change the physics of the problem.

      If I indeed divide the fluid volume to aim for a more structured meshing how should I define the contact between the fluid volumes? Bonded? Or should I define the fluid domain as a multibody part? I'm not a fan of multibody parts, since they have brought me some trouble in the past. I'm attaching a picture of my fluid domain:

      Hello I guess you are using Ansys meshing! You can make use of the Body of influence or sphere of influence sizing option available,if you don't want to split the geometry.
      Mesh> Insert > Sizing> Type : Body of Influence.
