Hi Folks,
i am trying to create a simulation with autorotation with the uses OF 1.6 extend and the GGI. Now i was trying to do some small changes in the rotation speed of my mesh but it will not work. for the beginning i tried do amke the speed time dependent by using the equation: rpm 10*sin(pi*time); but there was no effect. it was allways the rpm of 10 used. so i used some more easy expression: dynamicMeshDict: Quote:

Hi there,
A Good day to you! If I remember right, and if things are still the same as they were (which I am quite positive is the case), you cannot use expressions in your OpenFOAM dictionary files. For example, "10 + 10" does not work, because when OpenFOAM processes the dictionary files, it needs to recognise the fact that "10 + 10" actually is a mathematical expression, and then "solve" or "evaluate" the expression.... This functionality is not directly available within OpenFOAM. This could be the reason why you are always getting "10" as the RPM. Wishing you a great day ahead! Philippose |
