CFD Code with Fortran
Hi all,

I have a problem with F90 while writing a cfd code,

According to my code plan

1- Gridgen is post-processor and I export the unstructed grid as Ascii file and it is read with my cfd code and Ensight is post processor
2- My export grid data includes node location, boundary face and elements but according to the plan I have to define element's surface and surface relationships
I can determine the faces but I need a trick to complete my reader code

If you know can you explain how to sort the matrix(dimension 6x100000) ,
according to a colunm with fortran?

I really seek it and there is but I have not understood anything
