Rotating Freesteam

Hi everyone,

I want to simulate a pitching aerofoil in star-ccm+. I was messing around with dynamic meshes for ages but couldn't get it to work. I've been told an easier method may be to have the velocity inlet vary instead.

Does anyone know how to make the velocity inflow change during the simulation?

Thanks

field functions would do the trick... I would advise against this, however, it will be slower to converge and there are other issues that could pose a challenge. work some of the tutorials to figure out how to analyze motion.
