Massively parallel CFD code

I develop a massively parallel CFD code NFS based on the high order Flux Reconstruction (FR) scheme. With Fortran 2008, it is organized in the OOP way. Similar to the famous open source code OpenFOAM, NFS is a general CFD solver on the unstructured grid. It has been verified in lots of cases and is able to solve various cases with the user provided input file and grid.

Highlights of NFS include the following

Profession skills

  1. Proficient in C++, Fortran, Python

  2. Proficient in HPC environment and MPI

  3. During the undergraduate stage, I used CUDA to implement a Poisson equation solver and employed multiple core CUDA optimization tricks including coalesced memory access, reduced threads divergence and redirected data access to shared memory to obtain a good performance.
