I have a problem about cylindrical coordinate system.
I research axisymmetric jet, and I want to use cylindrical coordinate system in numerical simulation.
I will use direct numerical simulation in finite difference scheme (fortran).

In my university, there is an interesting book. The book name is "Paolo Orlandi, Fluid Flow Phenomena A Numerical Toolkit".
It has gzip file about program that would be helpful.
It was written in this book that "To compile the codes, in IBM or Digital computers.
What should I do to use these codes?

My computer has gfortran, so I modify the codes from xlf to gfortran in makefile.
Next I compile the make file, and I get following error codes.
in function `meshes_'
undefined reference to `__fentry__'

If you have knowledge about cylindrical coordinate system, Please tell me about it.

Thank you!

Thank you for reading this quetion!
I solve this problem to eliminate -p option in makefile.
The option has been abolished and is replaced to -pg.
But, I don't make cylindrical coordinate mesh.
So, please tell me bout it.
