macro substitutions in fvSolution
 
Hi guys,

for some reason I want to make this snippet work:(this is quite abnormal to do this but this is just an example)

Code:
PIMPLE
{ 
    nOuterCorrectors $nCorrectors;
    nCorrectors    3;
    nNonOrthogonalCorrectors 0;
}
But it does not! it says:
Code:

--> FOAM FATAL IO ERROR:
Illegal dictionary entry or environment variable name "nCorrectors"
Valid dictionary entries are
0
(
)
How can I make it work? thanks.

hello,

Maybe put the scalar definition outside the PIMPLE Dict ...

Hi,

The variable you are calling should be defined first, that's why it's complaining because the code can't recognize tha variable you call. I think that something like that should work instead:

Code:
PIMPLE
{ 
    nOuterCorrectors 3;
    nCorrectors    $nOuterCorrectors;
    nNonOrthogonalCorrectors 0;
}
Hope it helps!

Regards,

Alex
