"Too many grid points"

Description

Hello,

I am using v10.4 with GFS data. I am receiving the following error:

FLEXPART error: Too many grid points in x direction.
Reduce resolution of wind fields.
Or change parameter settings in file par_mod.

721 361

I have changed these values in par_mod. I have also checked with grep that these values do not appear in the file anymore. Yet, I continue to receive the same error message as above.

Could someone tell me what I'm doing wrong?

Thanks.

Maybe stiwari wants to answer, but my guess is that you simply need to do what the message says: increase the field dimensions in par_mod.

Yes, exactly.

This is related to the parameters nxmax, nymax, nuvzmax, nwzmax and nzmax set under "Maximum dimensions of the input mother grids" in the file par_mod.f90

These parameters should match the resolution of wind fields you're using as input.

Hi, stiwari,

Thank you for you response. Actually, my par_mod.f90 was in /src folder, but FLEXPART was in another folder (as i copy FLEXPART to other folder). I am not sure how my change in par_mod.f90 will influence on running FLEXPART.

Thanks

When you change par_mod.f90, you need to re-"make" FLEXPART. I.e. you need to create a new executable.
