Hello to the CFD online community,
I am trying to set up a simulation of an external flow over an aerodynamic hull shape using the academic version of ANSYS Fluent R18.0. I need to create a region -box-shaped- around the object and behind it (to cover the wake area) in which the mesh is more refined, such as that in the image that I'm attaching. I have been looking at tutorials in meshing topics, looking for a refinement regions or mesh subdomains...but I can't find how to do it. I attempted to create one by building a box with the geometry tools, but after trying different combinations of boolean operations (see screenshot attached) I can never use it as a subdomain inside the fluid domain, as it is seen as a different object.
In other CFD software I've tried there was a function for this, which consists of creating a "refinement box" around an object...I can't seem to find it in in Ansys.
Can anyone help me please? Thank you very much!
