Drag force calculation using URANS
Hi,
I'm working in my end-of-graduation-course paper, it's ,briefly speaking, a study about the flow behavior under a NACA0015 with a flap and gurney flap. Becouse of the size mesh and turbulence model, a steady state simulation do not converge (residual target 1e-6), so I used URANS. I know how to calculate the average of variables, but, here is my question, can I calculate the average of drag force? |
If I was doing this I would:
* Make a monitor point which had the drag force. * Run the simulation * make a solver monitor to display the drag force for each time step. Make the X axis time, not iteration number * Export the data to a csv file * Load the CSV into excel, matlab, python or whatever you use for mathematics and calculate time averages or whatever you want. |
thanks for answering,
I need to do the average of drag force acting under the airfoil,I think that this resolution will not work. Am I correct? |
You think the Resolution of what will not work?
|
no, my question is whether I can set up the bondary at CFX pre.
|
I do not understand your question. Can you say what your question is again, but more clearly?
