writing values to IOdictionary subDict not generating expected output?
Hello All,
Below I have the code that tries to output values to a dict file ( nevermind that it doesn't make sense in terms of actual scientific use as it's only for a reading and writing example). Basically I have a mesh that is read and some math is used to find scalars and I want to write this to a dictionary file in /constant.
Right now it just writes out the dimensions but not the result of the calculation
for volScalarField DVals = cellCentroid & cellCentroid;
Code:
#include "fvCFD.H"
int main(int argc, char *argv[])
{
#include "setRootCase.H"
#include "createTime.H"
#include "createMesh.H"
IOdictionary electrolyteProperties
(
IOobject
(
"electrolyteProperties",
runTime.constant(),
mesh,
IOobject::MUST_READ_IF_MODIFIED,
IOobject::NO_WRITE
)
);
dictionary& DDict = electrolyteProperties.subDict("D");
volVectorField cellCentroid = mesh.C();
volScalarField DVals = cellCentroid & cellCentroid;
DDict.set("values", DVals);
electrolyteProperties.regIOobject::write();
return 0;
}
