Hello,

I have made an interface between Matlab and CFX, so am running CFX from the command line. The command am using to start the simulation is
!"C:\Program Files\ANSYS Inc\v170\CFX\bin\cfx5solve" -def def_file_path.def -double -ccl ccl_file_path.ccl -fullname outbase_path

The command above is working without any errors and I get my output files but when am taking a closer look into the outbase_path.out I see even if I used -double command I get,

Added /SIMULATION CONTROL/EXECUTION CONTROL/EXECUTABLE SELECTION/Double
Precision = Off.

Am running a student version of CFX could this be the fault? Am very new CFX program.
I appreciate all help I can get to solve this issue

That is information at the top of the output file, correct ?

What does the setting says at the end of the CFX Command Language section says ? There should be an entry such as

Double Precision = On | Off

That is the final setting, and the one enforced on the software downstream.

Also, you can look at the ANSYS CFX Solver banner further down in the output file, and there should be a long string with information about the executable. Such string should say single|double...

Hope the above helps,

Hello,

Yes, thats information at the top of the output file, in the CFX Command Language for Run i got:
"SIMULATION CONTROL:
EXECUTION CONTROL:
EXECUTABLE SELECTION:
Double Precision = Yes
Large Problem = No"

Executable Attributes:
double-64bit-int32-archfort-optimised-noprof-lcomp

Since am using student version am limited to 128K nodes, but it really seems that it just using single precision because when am looking at the aspect ratio it says 100 (I read the CFX manual and it said something about that)
