ComplexVectorField

Induction · December 12, 2011, 08:03

Dear comunity,

I need to implement the possibility of calculating complex vector fields ( like for example the magnetic vector potential A) in OpenFOAM. I already recognized the ComplexVectorField.H library, which could be suitible for this issue.

Is somebody able to help me or give me an advice how to realize a simple calculation like this:

ComplexVectorField A;
(
IOobject
(
"A",
runTime.timeName(),
mesh,
IOobject::MUST_READ,
IOobject::AUTO_WRITE
),
mesh
);

solve(fvm::laplacian(A));

I offer my thanks in advance to all Members

I'm a little bit disappointed, that nobody wants to discuss this topic, but anyway i found in one previews threads an advice of henry to add a new geometric field. Had anybody allready tried something like this?

@piotr,

This post probably isn't going to help, but maybe someone else will find it as well. I did find the post

http://www.cfd-online.com/Forums/ope...ex-fields.html

that asks nearly the same question so you could ask them if they ever figured out the issue. Also, I found the post

http://www.cfd-online.com/Forums/ope...-equation.html

that might be of interest to contribute to the discussion there. The answer to this might actually be that you need to define an entirely new vol*complex*Field type...and I'm sure that will take some time to implement. Lastly, some of these "complex" questions take time to think about and answer. Good luck.

Thank you very much for your reply and your advice.
I allready started to implement a volComplexVectorField class and I was able recompile OpenFoam with this modification. But as I have written a solver using this new Field, I recieved some errors concerning fvMatrix files. I will try to solve this problems and keep you informed if I succeed.

I know that this is already a long time ago, but Induction, did you, or anybody else already implemented a "volComplexField" Function?
I need to solve for the complex Poission Equation for AC fields and need to solve for a complex scalar volume field

Did anyone ever have any success with this?

I want to solve the Laplace equation for conduction of AC current using phasors in OpenFOAM.
