Hello
I have a case with moving wall with constant acceleration! Which macro can define acceleration? I have written an udf for moving wall due to mass flow exit in a nozzle based on newton law (6DOF) but for a constant input acceleration...? Thanx |

I think you should calculate the instantaneous velocity based on Euler formula, that is: V/dt=F/m. "F" can be calculated via a macro or directly, depending on your physics and geometry. Goodluck Last edited by syavash; July 18, 2014 at 19:39. |
