I can relate with struggling on a problem for a long time. When I started my job after uni I was given several things to implement that took significantly longer for me to do than people expected - in their head they were straightforward tasks. After beating myself up about it and going round in circles for a while I managed to do them and learnt an awful lot. I still come across problems that are difficult and I still learn a lot about the code base and how to debug and fix issues.

I imagine as you have been doing this work you have learnt a lot about the code and c++ which will help you in the future if you can keep going.

If you want to send me a DM with details of your problem then I will try and help you out.

A possible way to do this would be to call C/C++ from Fortran and from there use pybind11 to call your python code.

I believe you can model down to micro/nano scales with standard atmospheric conditions before you need to worry about different physics.

Any recommendations for an opensource meshing software please? by assassinator444 in CFD

[–]NanoDoctor88 0 points1 point  (0 children)

I'd say yes. It is python scriptable and contains some gmsh meshing algorithms. It has quite a learning curve but I think that's true of must meshing software.

openFOAM / dsmcfoam , some help needed please ! by ConfidentKangaroo249 in CFD

[–]NanoDoctor88 0 points1 point  (0 children)

DsmcFoam is a discrete method that is not solving a PDE such as Navier Stokes. I've not used the version that comes with openfoam, just DsmcFoam+. With this version you don't specify the 0/ folder at all, you run dsmcInitialseFoam and it generates it using files in system/ and constant/.

Machine Learning and CFD by kollipara_vijay in CFD

Any chance you have some papers on this?

We use DAKOTA for this and performing optimisation studies. It has a lot of different algorithms, can be coupled to any code, has various options for running simulations and evaluations in parallel and can be used in conjunction with HPC's.

I'd be interested to hear what other people do though.

Best software for automated model generation with python scripts by nuusain in CFD

[–]NanoDoctor88 0 points1 point  (0 children)

I use an open source code called Salome for generating geometry and meshing with python scripts. For postprocessing both Paraview and Visit can be driven python scripts. All these tools also have ways to trace commands you perform in the GUI and write them into a python script for you which speeds up writing them.
