setting the 2nd order scheme in spatial and temporal discritization.
 

Hello, where I have to set, in Open FOAM, the 2nd order scheme in spatial and temporal discretisation?

Best regards!

You can set it in system/fvSchemes

Are there higher order, explicit runge-kutta schemes available in openfoam ? Like 3-stage or 4-stage explicit schemes.

Thank you Bernhard!
