Dear all,

I want to run cfx pre in matlab. so I wrote the following command in matlab:

system('C:"Program Files""ANSYS Inc"\v202\CFX\bin\cfx5pre.exe -line -def ./filename.def -batch filename.pre')

in which filename.pre is the session file.
but I receive the following error:
-- ERROR -- A simulation is already open! This must be closed before opening a new simulation.


ans =

0


Does anyone know how I can solve it? because I dont see any simulation running in my system
