Hi friends!
I'm trying to analyse a centrifugal compressor in ANSYS Fluent 14.5 so I'm using "match control" in ANSYS meshing for generating periodicity mesh! but when I'm updating generated meshing ANSYS says this error: "The mesher cannot find matching topology for following topology.please verify that the topology is the same shape and size. also verify the position and orientation of any associated coordinate systems." I checked the geometry and the faces are same for both sides and the edges and surfaces area are equal! Can anyone help me? |

it means the face you've selected it's not completely equal,
also sometimes ansys makes this error because the reference frame you've chosen for the matching control isn't valid |

I too had a similar problem. Finally, I got the solution to this.
Actually, I had to import a turbine blade (iges) and subtract it from a domain created in Ansys DM. When I first imported the geometry and then made the domain in DM, the Mesh module showed the same error. I think importing the geometry into DM may change the coordinate system at times creating slight error, which I confirmed by creating a new coordinate system (using Type:From Coordinates and selecting a vertex which had to be on axis - but this was off-center which created the problem). Solution: First Creating the domain/ dummy sketch in DM and then importing external geometry resolves the problem. Shubham |
