I use star-cd 3.22/mixpert 1.0 with absoft pro 9.0 to solve mixing vessel problem. When I finish the geometric construction and mesh definition and press "process" or "Est mesh #", an error message as following

(name of the mix-file:

while executing "exec echo.exe $casename | $mixpert_exe"

(procedure "tkButtonUp" line 7)

Thanks!!
