export time steps for ensemble averaging
 

Hi all,

I have simulated a DES of a Karman vortex street and want to ensemble-average my results over time steps. So I made a fourier-transformation to get the right periodic time step and wrote several timesteps out of it (in every period 20).

My first idea is to export only for one averaging the needed time steps ( 1 21 41 61...) and to average them in ensight).
So is there a possibility to export only e.d. the 20th time step?

I'm using starCD 410

Thanks Thomas
