snappyHexMesh for Sloshing tank-reg.
 
1 Attachment(s)
Hi,
I'm using the snappyHexMesh for the first time. The problem i'm dealing with is, sloshing tank with a vertical baffle placed at the mid length. The issue i'm facing is, after meshing with snappyHexMesh, i could not see any baffle( Baffle CAD file named as tank.stl) patch when i open it through paraFoam. I could see only the walls patch (walls of the tank) in the list. I've attached herewith the Dictionary i'm using.
Kindly suggest me your opinion on the possible cause of issue.

Thank you,

Hello all,

I could correct the issue. Sorry, i did not notice that baffle was not present inside the tank domain (dimension mismatch). But one doubt is, i've used 250mm (0.25m baffle height required) baffle height while creating model in CATIA to fit into the tank of 0.75m height in OpenFOAM. But the dimensions did not match while importing to OpenFOAM. Could you tell the possible reason?

Thank you,

Probably CATIA export stl model in milimeters not in meters and there is an option to change export units to meters.
You can also scale stl file after export using surfaceTransformPoints utility.
