I have a made a geometry to simulate the flow around a cylinder using FreeCAD and exported it as .stl file. I am confused how to proceed next? I am using pitzDaily case directory for this simulation. Where to begin my simulation and which all files I need to alter?
I tried to change the vertices in blockMeshDict file but I failed. Can there be a technique in which I can import the stl file and the vertices can be updated automatically. Since, my geometry seems complicated after exporting it through MeshLab and there lot of vertices mentioned which I can not understand.
