Crating and using a personal tool or aplication
 

Hi everyone! I have this doubt. I want to programme a tool for post-processing my results. I want to compute shear stress in the boundaries for a laminar case. Since the tool provided by openfoam is for turbulent flow, i have to programme it myself. The question is, how do i create a new application? i mean, where and as what type of file? And then, once created, how do i run it.

Thanks a lot!!!
