stilll on particle tracking

simone marras

This is me again, I posted a quesiton on the particle tracking algorithm and how to apply it to water droplets.

The Tutorial "flow through a butterfly valve" is well explained and it solves quickly and esily, but when I finally try to apply my own geometry, i get immediately the error messages right after launching the simulation with the exsact same parameters: (my geometry is simple: (it is an aerodinamic cilindrical wall coaxial to an external larger case with a diameter of 26 mm).

What could th eproblem be? can it be the mesh made in Icem?
