Is it possible to read in a vo
 

Is it possible to read in a volScalarfield from a
data file (in the constant directory) during the run and if yes, how can this be achieved?

Thanks in advance.

Yes, instead of say vol
 

Yes, instead of say

volScalarField p
(
IOobject
(
"p",
runTime.timeName(),
mesh,
IOobject::MUST_READ,
IOobject::AUTO_WRITE
),
mesh
);

use

volScalarField p
(
IOobject
(
"p",
"constant",
mesh,
IOobject::MUST_READ,
IOobject::NO_WRITE
),
mesh
);

Thank you very much for your h
 

Thank you very much for your help. Originally I replaced runTime.timeName() by runTime.constant(). The results are identical.

I set up the file defining the field beginning with:

dimensions [...];

internalField
nonuniform (
.. here the values are inserted
)

What I know is that I have to insert the values for the interior cells. But, in what order? And how do they relate to the cells and their indices, respectively.

I would like to specify the values in the same ordering as for the cells (polyMesh/cells). Is it possible? Is there a chance to define the values for the entire mesh, not only for the internal and boundary fields, e.g. by using a different keyword, e.g. Field ...?

Come on, this is trivial: the list of values is in the same order as the list of cells: first value into first cell, second value into a second cell etc. Anything else would be madness.

P.S. For future reference, think about your problems: if it is logical, it is probably right!

Hello,

I've asked about how to create and use a new volScalarField on a drag model.

But now, I solved. I did it creating the variable on createFields.H, and later, calling it on the drag model file using lookup, command.
