Hi,
I am trying to do tutorial 16.2(LES of turbulent channel flow). I am able to run the code successfully. But, while post processing I am using my stand alone code to average the velocity over each slice in y-direction by processing the exported tecplot data file. I am observing a 10% error in the results. But, when I run the MACRO script given in the tutorial I get the correct results. I tried to check the MACRO script and observed that while averaging the LES data the velocity is added for a cell set of 1350 for each y-slice and is being divided by (30x50=1500). I think this is where the 10% error is vanishing. Did anybody had a similar problem? Does anybody know the reason behind it? I even checked the velocity at the midplane which is over 21 m/s but in the plot from star-cd the maximum goes to about 19 only. |
