SetFieldsDict: Non uniform density
 
For my simulation I have a circular density area that i would like to put a
gaussian density distribution inside. To do this I am trying to use codestream inside the setFieldsDict. Below is what my dictionary looks like.

FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "system";
object setFieldsDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

defaultFieldValues
(
volScalarFieldValue rho 1
);

regions
(
sphereToCell
{
centre (0 0 0);
radius 1000;
fieldValues
(
#codeStream
{
codeOptions
#{

#};
codeInclude
#{

#};
code
#{

#};
}
volScalarFieldValue rho 100
);
}
);

But when I run setFields i keep getting this error:

wmake error: file 'Make/linuxGccDPOpt/objectFiles' could not be created in /home/adparo/Documents/MultiTest/multiTest2/dynamicCode/_a45e8e741fc6fd0ed5b8baeed94b2e884fb3af7e

Am I allowed to use codestream in setFields and if so what am i doing wrong.

So I edited the file so it now reads:

regions
(
sphereToCell
{
centre (0 0 0);
radius 1000;
fieldValues
(
#codeStream
{
codeOptions
#{
-I$WM_PROJECT_DIR/src/finiteVolume/fields/volFields\
-I$HOME/Documents
#};
codeInclude
#{
#include "volFields.H"
//#include "volFieldsFwd.H"
#};
code
#{
scalar x= 0;
//vector centre = (0 0 0);
//#include "createRad.H"
//volScalarField rhoi = 100*e^(-rad/1000)
#};
}
volScalarFieldValue rho 100
);
}


and is now giving me this error:

could not open file volFields.H for source file codeStreamTemplate.C
/home/adparo/Documents/MultiTest/multiTest2/system/setFieldsDict::#codeStream:32:23: fatal error: volFields.H: No such file or directory

I have the path to the exact file listed in codeOptions but it still cannot find the header file. What am I doing wrong?
