Programming guide for custom data types

fmilicchio · June 21, 2018, 06:49

Dear all,

I have played with OpenFOAM and customized my very basic first solver (icoFoam) as suggested by the tutorials I have found online. Now my basic knowledge isn't enough to move forward. I've searched online but no tutorial/source code is available (*) that answers this question:

How can I implement custom matrix/vector classes?

For instance, I'd like to use CUDA to perform some computations, and a tutorial on how to achieve this would be quite useful. Of course, I'd like my classes to be used by OpenFOAM's algorithms, but I don't know if it's technically feasible (being also performant is another step).

Thanks for any pointers!

(*) PS. I am aware of RapidCFD, but it seems a fork of OpenFOAM, too much probably to begin with.

Thanks, zhangyan.

I have successfully compiled foam-extend-4.0, and CUDA solvers in src/.

It seems, though, I cannot find any tutorial on how to use the included CUDA solvers.

Any hints about this?

Thanks!
Franco

Sorry, I haven't used it.
