Hello, kind regards to the Ansys Community.
For several days, I have been trying to simulate the air flow through this hood expecting to accuaretely determine the pressure drop. At first I try simulating an imported geometry from Solidworks, then I substracted this geometry into a cubic domain and finally I try modeling the hood in Design Modeler; all with the same result (or error). Once the geometry complement is checked, I logically move on to the meshing, in which the automatic meshing throws an acceptable skewness. Everytime I try to open the "Setup", this error appears:
The hood geometry is actually not that complicated, reason of why I fail to understand the origin of this error. For the geometry modeled in Design Modeler I decided to use a Simmetry condition, so it visualizes as it follows:
I pretend to apply a border mass flow condition to one end of the duct, then an opening condition to the hoods, and last but not least, the simmetry condition at the longitudinal cut. Nevertheless, in the "Setup" after the error message pops-up I can only visualize this:
As final notes these are the meshing characteristics and I am using CFX instead of Fluent for beginner's choice as it seems friendlier to work and the computational requierements that (as I have investigated) are supposed to be lower.
Average skewness: 0,515.
Thank you for your time and support, sincerely
