Problem implementing runTime Selection
 

Hi all,
I am trying to implement a model using runTimeSelection as per this link http://openfoamwiki.net/index.php/Op...tion_mechanism, especially section using section 4.3 as a guide.
But the subsection http://openfoamwiki.net/index.php/Op...es_to_registercauses a compilation error:
Here basicIgnitionModel is my base class, and NoIgnition is one of the derived ones.
Is there an implementation in OpenFOAM source that I can look at?

Hi!

Can you post the code line which is causing the error?

Hi Adhiraj,

The actual implementation of runTimeSelection (RTS) is hidden in OpenFOAM using a series of macros, such as addToRunTimeSelectionTable and defineRunTimeSelectionTable. So you never actually see it. This page of the wiki pulls out these sections and reconstructs them for all to see.

Section 4.3 of the wiki was not intended to be directly implemented in your code. It's just supposed to show you what's going on. But I have managed to get RTS working this way - so it is possible. What I suggest is you try using the macros. The basic ones outlined in the first few sections of the wiki page should work. If your base class or derived classes are templates, then things get more challenging.

Examples are everywhere in OpenFOAM.

Straightforward to follow:
Base: src/turbulenceModels/incompressible/RAS/RASModel
Derived: src/turbulenceModels/incompressible/RAS/kEpsilon,
Derived: src/turbulenceModels/incompressible/RAS/kOmega

Buried deep in other macros - hard to figure out:
Base: src/thermophysicalModels/chemistryModel/chemistrySolver/chemistrySolver
Derived: src/thermophysicalModels/chemistryModel/chemistrySolver/EulerImplicit
Derived: src/thermophysicalModels/chemistryModel/chemistrySolver/ode

Hope this helps!

Thanks to both of you
Yes, and thanks for the guide. The Wiki guide was enough for my earlier work.

I tried using that part because I wanted to use templated bases and derived objects. I changed my mind and figured out a different way. So once again the first few sections should suffice.

Yes, I agree. These are indeed the functions/files I looked at before implementing the runtime selection for my earlier model.
