codeStream in SetFieldsDict
 

Hi Everyone,
Im trying to initalize a non uniform density region inside set fields using the codeStream command shown below:

defaultFieldValues
(
volScalarFieldValue rho 1
);
regions
(
sphereToCell
{
centre (0 0 0);
radius 1000;
fieldValues
(
#codeStream
{
codeInclude
#{
#include "createRad.H"
#}
code
#{
volScalarFieldValue alpha1 10*e^(-rad/1000);
#}
}
);

}
);

but when I run setFields i get

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

Is it possible to use codestream in setFields and if not is there another way to do this? Later on i need to initalize with multiple density regions on my mesh each with different densities.

Just follow the instructions in the error information:
adding to the InfoSwitches setting in the system controlDict(not the case controlDict):
