[GAMBIT] Structured mesh around hole

prince_pahariaa · June 20, 2012, 07:44

Hey Friends,

I am trying to achieve structured (HEXA) mesh. Here is explanation of geometry.

There is a L pipe coming from outside and entering into rectangular pool. There is 10 nozzle mounted on the the part of pipe which is inside the pool (Nozzle is mounted on horizontal side).

I can create this simple geometry but i cannot create hexa mesh around it (near nozzle part and in rectangular pool as it was created by split operation). Can anyone suggest how to create (or decompose) geometry so that it can be structured mesh

If structured mesh is not possible suggest which mesh will be better.

Here is picture of my model..

Looking forward for any suggestion

structured should be possible, but you will have to spend some time on it.
Else you can mesh it with tetra-hexcore with size functions
Decomposing your volume, will allow you to put more hexa subvolumes.
Mesh with tetra hexcore only, where you see you will have difficulties to mesh with hexa (especially a pipe junctions)
