KNOWN ISSUE: MUSIG model simulations can give solutions that are strongly machine dependent (Class 3 Error)

When using equal mass size group specification for a MUSIG fluid, coalescence may lead to bubbles of mass 'equal' to the maximum mass. Whether coalescence takes place or not, with consequent very different solutions, is then determined by whether the size of the coalesced bubble is actually greater or smaller than the maximum mass.

The coding doesn't allow for the model depending on this rounding error.

No workaround is currently available.

ANSYS CFX Release 14.0. A custom executable for ANSYS CFX Release 13.0 SP2 is available on request.
