I want to calculate the rms of dp/dt,so i want to know if it is possible to calculate dp/dt then use the average field function to calculate the rms value of dp/dt
or use the function ddt2 for calculating (dp/dt)^2 but after than the fields need to be summed for all time step does anyone any ideas how it can be calculated in openFoam? the formula is in the following link http://drive.google.com/file/d/1tYkR...ubkcSxjo4/view |
