My gambit geometry of one volume contains a large tank with small pipes. Using tet hedral meshes, with meshsize >20 some parts of pipes are not going to mesh and i can not export to fluent . And with meshsize=<20 refining volume becomes very very time conuming almost hanged on 16%.

Try to divide the volume so that you can manage the mesh generation and quality properly.

Hello,

you might try a sizing fixed function. Choose the pipe surfaces as source, and attach your sizing function to the volume. Play with the start-size, size-limit and growth-rate. Choose the distance large enough: your entire volume should lie withing the sizing-function-region.

Are you sure your geometry is correct? Do you want to model a flow in the pipes? If you have a flow inside your pipes and in your tank, you really should have more than one volumes.

good luck,

with the whole geometry as one volume it took for mesh size 22 a whole night to refine in Gambit on my PC. Thanks!

waaaaw!

how big is your mesh now? How much memory has your pc? Is your mesh of good quality?
