#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?

#255 duplicate Using GFS 0.25deg Data mradenz
Description

Hi all,

has anybody ran Flexpart 9.0.3 successfully with GFS 0.25 degree data in grib2 format? (e.g. from here: https://rda.ucar.edu/datasets/ds083.3/#!description)

After compiling with par_mod.f90 set to the larger grid integer,parameter :: nxmax=1441,nymax=721,nuvzmax=64,nwzmax=64,nzmax=64, the error with t not in [K] occurs for any input data (1deg or 0.25deg, both grib2). Hence I suspect a problem related to the grid size.

Any workaround? Thanks in advance, Martin

#257 duplicate Issue with warm start nehstand
Description

I am using Flexpart 10.4 and am trying to restart from the positions of the last simulation in partposit_end. But I am not sure how to modify the RELEASES file for the simulation to run. When I try to set PARTS = 0 (Total number of particles to be released), I get the error :

FLEXPART MODEL ERROR RELEASES file is corrupt. At least for one release point, there are zero

If I try to set PARTS = 1, I get :

##################################################### #### FLEXPART MODEL SUBROUTINE RELEASEPARTICLES: #### #### #### #### ERROR - TOTAL NUMBER OF PARTICLES REQUIRED #### #### EXCEEDS THE MAXIMUM ALLOWED NUMBER. REDUCE #### #### EITHER NUMBER OF PARTICLES PER RELEASE POINT#### #### OR REDUCE NUMBER OF RELEASE POINTS. #### #####################################################

I also tried to set NSPEC = 0, but then I get

#### FLEXPART MODEL ERROR IN READPARTPOSITIONS#### #### THE NUMBER OF SPECIES TO BE READ IN DOES #### #### NOT AGREE WITH CURRENT SETTINGS! ####

Any help will be appreciated, thank you!
