I wrote a little couple of programs, respectively in Fortran and C++, as a proof of concept for connecting a Fortran program to a sort of visualization server based on VTK. The nice thing is that it uses MPI for the connection, so on the Fortran side nothing new and scary.

The code (you can find it at https://github.com/plampite/vtkForMPI) and the idea strongly predate a similar example in Using Advanced MPI by W. Gropp et al., but makes it more concrete by adding actual visualization...

In previous posts of this series I presented an elaboration of the Musker-Monkewitz analytical wall function that allowed extensions to non equilibrium cases and to thermal (scalar) cases with, in theory, arbitrary Pr/Pr_t (Sc/Sc_t) ratios.

In the meanwhile, I worked on a rationalization and generalization of the framework, derivation of averaged production term for the TKE equation, etc.

While the new material is presented in a substantially different manner and will...

At the following link:

there is a basic MATLAB tool to handle unstructured finite volume grids (fluent .msh or .cas files) and to perform basic interpolations, gradient computations, plots etc. No actual FV computation is ever performed or implemented, however, the main structure of the code is clearly there.

GENERAL DESCRIPTION

The tool is actually a collection of functions, grouped by tasks...

If you are looking for something more didactic, i suggest:

But it seems that the material is not available when the course is not active.
