We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Dear Devendra,

I modified the Poisson’s ratio of the involved body. Then, I checked (check geometry) the whole body, no geometry problem found. Then, I extracted the control volume selecting the inlet and the outlet of the flow and first path of the flow (in blue). Then, I chose boundary condition (i.e. temperature and mass flow) and fluid (gas) and tried to launch the solve to get a fluid simulation. Unfortunately, following several minutes of running, the result is a message labeled in red: “A meshing error has occurred. Use check geometry to identify common problems such as a small faces, overlaps, etc. Increase the solution fidelity or add local fidelity controls to capture small features if required”.

Then, in yellow: “Surface bodies will be excluded from the simulation (1 body)”, with no further explanation.

Further, on the check geometry panel (lower right end side): PartBody/Hole.1 in yellow: (1) Geometry self-intersects

PartBody/CloseSurface.1 in yellow: (1) Geometry self-intersects

in blue (1)Edge is inexact and not lying on face

Then, Volume: 

in red: (17) Face intersects another face

in yellow: (2) Geometry self-intersects..

Unfortunately, and different from the Ansys Courses I watched, the Check Geometry panel had the SOLVE soft button disabled, thus I had no chances to realize which are the surfaces and volumes involved. The images I’ve taken are too large to be shared. I would really appreciate your further support as the intake is really driving me crazy (I’m still working on it since 3 months and no results)…

I've another message, stating DVI variation (3mm). Could you explain it? 

 

Thank you,

Nicolino
