hi Bernhard,
thank u, that i know schemes are available in system/fvSchemes, but how to write a code for a new scheme to replace existing euler or upwind schemes, or to modify the existing schemes.

Than you can take a look here:
/src/finiteVolume/interpolation/surfaceInterpolation
and here
/src/finiteVolume/finiteVolume/ddtSchemes

But are you sure you really need this? Because all of the common schemes are already there. It think the way to do it, is to build a library for your special scheme, that you can load via your controlDict. Good luck
