HEY dim
have you found the answer? |

The magnitude of the average wall shear stress vector has to be calculated either using a UDF or in a post-processing tool(.e.g Post-CFD, tecplot etc). regards, Dimitrios |
Are you calculating OSI? If so, it would be interesting to know your approach.

I was traveling and I missed this one. Well... over the years I have tried both approaches (use of udfs/UDMs vs tecplot/matlab) and I would say that I really prefer the first one, since this way you can avoid problems related to the need of saving huge amount of data over time to avoid introducing errors in the osi/rrt calculations. Unfortunately, I don't have the code I used while I was working on biofluids because I have moved to another institution but it shouldn't be very different from the following: Code:
#include "udf.h" /**** mandatory I hope it works for you too. some more tips: 1. You may want to exclude the initial period(s) from the osi computation as the results will be affected by you initial conditions (u=v=q=p=0??). 2. Keep monitoring OSI/ RRT statistics (max, min, average) to make sure that your results are period independent. Best regards, Dimitrios |
