I have generated a model in proe for a Shell & a tube attached at bottom of shell (Simple Geometry)
Exported as solid in STEP & imported in GAMBIT, applied Grid & Boundary Conditions & exported a mesh for fluent 5/6 While reading in Fluent 6.1 & checking that grid, getting message as "there are non-positive volumes" & checking fails, still I am going for analisys and getting error as diverged solution I am not able to understand the error, please help me out. Also how to give grid in shell thickness?? or just to provide a surface as shell thickness?? |

Open the mesh in GAMBIT and check all volumes.
This will allow you to understand where the problem is. GAMBIT will list all volumes which are not valid. Hi ap |

How to check in Gambit for non valid volumes, can I create a volume for thickness for a tank model imported from PROE as STEP/SOLID?

To check volumes in GAMBIT you have to enter the section to create 3D geometries (click on the cube in the Geometry bar), then right-click on the i icon, and select the Check function (with the V-like symbol).
Click on that button, select all volumes you want to check and click on Apply. GAMBIT will list all valid and not valid volumes. Hi ap |
