# nek-utils   

A place to put my codes for Nek5000/NekRS.   

All tools are under a separate directory or a git-repository with README.md description and with proper example(s).   

This is still under-construction. 

Most codes are based on existed Nek5000 code. 

I will put proper reference and lisence later.

Some codes are experimental. Feel free to report issues and bugs.   

Please use this as a dictionary to other repositories.

I suggest to use the latest/release version from repositories. The submodules might not up-to-date.

## Overview

- `machines_list/`

   - __Main__: A place to put all of my scripts on server/machines

   - __Usage__: Using scripts from a stranger is dangerous. Use them at your own risk.   

   - __TODO__: Those scripts might not be up-to-date. Please contact me if you face issues.

- `nekrsExamples/`

   - __Main__: Extra examples for NekRS. Focusing on realization of Nek5000 functionality inside NekRS

   - __Usage__: See independent examples.

- `usr_extra/`

   - __Main__: This store those isolated `*.f` files that I usually use is to do some checks or post-processing

   - __Usage__: Include the file in .usr file. See the README.md for individual subroutines.

   - __TODO__: I just start collecting them together. Will remember to copy files here when I see them.

- `outpost-select/`

   - __Main__: A modified nek `outpost` allowing user to only dump the user-selected elements to reduce the size of the output file and the visualization cost.   

   - __Usage__: independent file included from a nek user file.   

- `nek_connectivity/`

   - __Main__: Extra nek tools for the connectivity file `.con/.co2` such as `n2to3` and binary-ascii translation.   

   - __Usage__: [repo] Modified nek5000 tools.   

   - __TODO__: Merge into `n2to3`   

- `SphereMesh/`

   - __Main__: Mesh generator for pebble bed geometry.   

   - __Usage__: [private repo] A workflow contains MATLAB code and nek mesh smoother.   

   - __TODO__: WIP, to be released in future  

- `Tet2Hex_forNek/`

   - __Main__: [repo] Mesh generator for arbitrary input points via tet-to-hex. 

   - __Usage__: MATLAB code that generates nek meshes.

   - __TODO__: Add new features as a small subset of SphereMesh      

- `quick_fix_boundary_layers/`

  - __Main__:  fix the boundary layers for cylinder geometry   

  - __Usage__: independent file included from a nek user file. 

  - __TODO__: clean up, add general geometry

 

- `del_elements/`

  - __Main__: delete selected elements from mesh in nek

  - __Usage__: independent file included from a nek user file. 

  - __TODO__: add feature like BC tracing and dump co2 files

- `p3d2nek/`

  - __Main__: converting plot3d mesh to nek meshes

  - __Usage__: [repo] MATLAB scripts

  - __TODO__: See the README

  

- `OneSphere/`:

  - __Main__: mesh generator for single pebble

  - __Usage__: [repo] MATLAB scripts

## TODO:

- mesh smoother   

- mesh refine / extrusion

- multi-box reader

- hpts example(s)

- web based doc

- gallery and showcases

- SEM codes (both MATLAB and Python)

- external storage for large files
