Hi guys,
I am new in OpenFoam and I need to change an instruction in a already written boundary condition with groovyBC.

I am using the solver coldEngineFoam in order to simulate a gas spring (a piston compressor without valves).
I want that a value of pressure is variable with time (sinusoidal) in this sub model, now is constant.
In order to do this I need to take the crank angle at the current time step. Anyone knows how to do? I attached a screenshot of the instruction tried by me but it doesn't work.

Thank you in advance.
