using parameters in blockMesh
 

Hi everyone,
I've used following commands in my blockMesh dictionary in order to modify my geometry easily:

D 5.0;
L 100.0;
halfAngle 45.0;
radHalfAngle #calc "degToRad($halfAngle)";
R #calc "$D/2";
CW #calc "$D/4";
CX #calc "$R*cos($radHalfAngle)";
CZ #calc "$R*sin($radHalfAngle)";
NPS 3;
NPD 3;
NPY 10;
(complete blockMesh Dict is attached)

But the following error appeared in terminal:


FOAM FATAL IO ERROR:
Loading a shared library using case-supplied code is not enabled by default
because of security issues. If you trust the code you can enable this
facility be adding to the InfoSwitches setting in the system controlDict:

allowSystemOperations 1
The system controlDict is either
~/.OpenFOAM/$WM_PROJECT_VERSION/controlDict
or
$WM_PROJECT_DIR/etc/controlDict

file: /home/amir/Desktop/cavity.pipe/constant/polyMesh/blockMeshDict from line 17 to line 21.

in file db/dynamicLibrary/dynamicCode/dynamicCode.C at line 81.
FOAM exiting


what should I do?
any help is appreciated.
best regards,

Greetings Arjang,

The detail is that you need to turn on "allowSystemOperations".
I've written about this some time ago... read this section: 2.1 Additional tuning

thank you Bruno;)

thank you its helping
