f90 program for the creation of a nek5000 .rea file for the creation of a good mesh for a straight pipe
The software generates a mesh based on the parameters in the file INPUTgeometry. One example file is provided.
Both a 2D and a 3D mesh are generated in base2d.rea and base.rea respectively.
The created mesh can be visualised by running the python script plotMesh.py. The script directly reads the .rea file base2d.rea and can be run simply by executing
python plotMesh.py
The pymech suite (automatically fetched) is used for reading the .rea file.
