Hello，everyone！
I am a newcomer to openFoam. I don't how to define inlet velocity function. For example v=0.45-2x^2 or v=2t. My openFoam version is 2.1.1. Best wishes. |

An easy way is to set the b.c. for each cell using your formula.

groovybc in swak4Foam (http://https://openfoamwiki.net/inde...am/Downloading) is an easy way to code your own boundary condition as a function of position.
