When using the CEL variables 'diami' and 'diamj' in a MUSIG fluid simulation, CFX-Pre requires the musig fluid prefix. However, when the resulting Definition File is run in the solver the following error is generated in the first iteration:
ERROR #001100279 has occurred in subroutine ErrAction.
NAME_MOD: Error finding variable "DIAMI_MF1"
There is a conflict in the way these variables are handled by CFX-Pre and CFX-Solver. CFX-Pre requires a musig fluid prefix, but the solver requires this to be absent.
Either ignore the errors in CFX-Pre when writing a Definition File, or edit the CCL in a Definition File writen without errors from CFX-Pre and remove the musig fluid prefix.
