Hi all.
I am working on a venturi tube in which Water is coming from inlet 1 (main inlet) and air from inlet 2 (Neck).
After transferring mesh from ICEM in checking mesh of Fluent:
This warning appears:
"number of left-handed faces detected on zone x is not equal to the number of Right-handed faces on zone x. (Attached below)

Model
Multiphase VOF and CLS
No mass and energy transfer.
I initialized using standard from inlet 1. Then to run calculations it stopped with "floating point exception" error.
I surmise the problem is with my mesh.
Does anyone know how to solve this to avoid floating point exception error while calculation?
Thanks in advance

Hi dear NSTD,
Yes. Actually I used fill by caps in design modeller and in ICEM, the only block contains all the fluid volume.
There is one body I named FLUID DOMAIN.
Thanks
