grids in tip clearance
 

hi,everyone.

my model is a axial pump,and the tip clearance is very short to the whole radius. and i met a problem for grids.

when i make ogrids for blade,i don't know where to put the ogrids vertices between the shroud and blade tip. and some grids are always wrong with small angel ,such as 0-9 degree. how to avoid this situation?

thank you very much!

Do you really need a grid in the tip clearance? Most of the time a tip clearance model is quite sufficient, avoiding the trouble to create a grid in that region. If you really want to grid it, you will need a more complex multiblock topology (assuming you are using structured grids), to get a grid of good quality.

thank you very much! i have finished the structrued grids:)
