eno is on a distinguished road
I am using openfoam 1.4 in cygwin to solve internal compressible turbulent flow under the motion of a piston. By modifying rhoTurbFoam I can use oscillatingFixedValue in cellMotionUX to define a sinusoidal piston motion Ux = f*(a*sin(2*pi*t)+1). The mesh deforms as expected and the simulation looks reasonable.
Now I want to drive the piston with motions (time varying, no sinusoidal displacement) measured from experiment. How can I do it?
