Dear Foamers,

one short question:
Is it possible to calculate velocity components via funciton object during runtime? (Just as it can be done for postprocessing by "foamCalc components U" )

Thx!

Can't rule out that there is a functionObject in OF that does it. I do it with an expression "U.x" in the expressionField-functionObject of swak4Foam. But I'm extremly biased in that matter

In OF 5 and below you have

Code:
foamCalc -components U
This does it for all the times, you can specify using -time flag a specific time.

In OF 6 it is

Code:
postProcess -func "components(U)"
