CFX from Matlab Error
 

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

Is there a lock file (.lck) present in your working folder?
This might prevent opening the definition file. Therefore delete it and see if it helps.

Also, check that your script (filename.pre) does not open a .cfx file and then open another one (or start a new one). I think that gives the error you describe. You have to close the first cfx file before you can open a new one.

On top of that: I think you should read .cfx-files and write .def-files. Is that what you do?
