Hi all,

I have a modified turbulence model where I calculate (lets say) values stored in a IOobject xObj. How can I make this xObj now available to a modified interFoam solver?
I know that I can use e.g. the nut in interFoam via turbulence->nut(), but how can I achieve this behavior for my xObj? I think it must be registered somewhere, but I don't know how to do this...
(Writing the variable onto disc every single time step and reading it in again is not an option as its too slow.)

Thanks for any hints,
Arne

Hi Arne,

Maybe this can help: http://openfoamwiki.net/index.php/Snip_objectRegistry

Hello Arne,

I think you need to include the library header for your object in the custom solver. Then you can define a similar "nut" function in your turbulence model that returns a copy (or the address) of the object. Then you can declare an object in the solver and it would go something like (in solver):

object myObject;
myObject = turbulence->myObjectFromTurModel;

Where in the turbulence model you have:

object kOmegaBlaBla::myObjectFromTurModel()
{
    return myObjectFromTurModel;
}

If the object is large you can make the function "int" and return a pointer to the object (tricky!)

Hi all,

I indeed had to make an object registry, as "simply" making a new entry in the turbulence model did not work, as the RASModel class is fixed to the given variables and cannot be expanded.
The (so far) working solution is given here: http://www.cfd-online.com/Forums/ope...tml#post380045
