Mean Forcing - Inclined Wind velocity
« on: March 30, 2015, 07:34:29 am »

Hi,
    I am in need of exploiting the mean forcing of fds to simulate inclined wind velocity (refer 6.4.3 of fds user guide) in pyrosim. Kindly provide little advice on the same.

Awaiting a positive response

Hello,

Please see the attached example file where I have applied a 2 m/s MEAN_FORCING flow in the domain.  Look in the the "FDS" > "Simulation Parameters..." dialog's "Misc." tab for the advanced records that create the flow condition.

The U0 and V0 values are the X and Y axis components of the intended flow vector.

Best Regards,

Thank you Bryan,
It worked well.
Also, is it possible to add atmospheric profile to mean forcing?

Thanks

I see that you have your reply from the FDS developer.
https://groups.google.com/d/topic/fds-smv/ZUxnFY-5tzs/discussion

This feature will be in FDS 6.2.0 which they say should be released in a week or so.  It can take some time for PyroSim to catch up with the changes in FDS 6.2.0, so you may have to run from the command line according to the instructions in the FDS User Manual until we have compatability.
