#83 fixed FlexWRF runtime error jbrioude Peter_D
Description

Hi,

I would greatly appreciate your help with the following runtime error:

I have run WRF V3.3 and, in attempting to run FlexWRF using the WRF output, I get the following fatal error:

FLEXPART WARNING: NO WIND FIELDS ARE AVAILABLE.

I have checked my WRF output variable listing and compared it against the required variables for FlexWRF (as per the Brioude et al , 2013 paper in Geosci. Model. Dev.). I can also view the WRF output variables, so the data have been generated. I have even tried running with a larger nest, but get the same error.

Previously, I ran FlexWRF successfully run for the testcase (i.e. with Flexwrf.input.forward1 and the downloaded test WRF output files), so I am certain that it is not a compiler issue.

I have attached my input file, log file and output header file.

Thank you in anticipation for your kind assistance.

#240 fixed FLEXPART-WRF particle height does not change for 16 hours pesei ZhenhuaHao
Description

Hi there, I am using flexpart-WRF to simulate particel trajectories and what come out seem unnatural and may be casued by some issues.

The altitudes of all particles keep increasing for first 8 hours (10am to 18) and then remain at exactly same altitude for another 16 hours (18-8) before increasing again. The last recorded altituedes are often far off the ground (above 200 m).

I changes my WRF inputdata to different dates and files but it keeps having the same problem. So could you please be possible to advise any potential issue causing this?

Thank you so much for you help and support in advance.

Cheers, Iris

#245 worksforme particles below ground are reflected ZhenhuaHao
Description

hi there,

I reaslise that in subrountine 'advance.o', all the particles that below the ground are reflected which means they are moved back to the altitude above ground. I could understand this setting for gas, but maybe not for some particles, and it make no sense for my case when I am simulating seed dispersions.

So I would suggest to set up a switch to do reflection or not.

If I want to fix in my own version, could you comment on how to fix it in the most simple way?
