Class 3 Error

SYMPTOM:
In a PTM calculation with a stage interface, particles that cross the interface may appear to be clustered in regions where the grid is finer, thus producing more effect on the continuous phase in these areas.

PROBLEM:
Particles that cross the interface should continue from random azimuthal positions with the same axial and radial positions. However at present the code continues the particles from a random element face in the azimuthal direction, thus giving a concentration of particles in areas where the


WORKAROUND:
No workaround is available.

FIXED IN:
ANSYS CFX Release 12.0. A custom executable for ANSYS CFX Release 11.0 SP1 is available on request.
