WPS4.6 /with ERA5/ problem with metgrid.exe

hello, I've been using WPS4.3.1 so far, using ERA5 pressure levels and single data, and creating a metgrid (I used Vtable.ECMWF). Now, after updating to WPS4.6, ungrib works correctly, but when I run metgrid.exe, the met files are 15 kb each.
 
Please run WPS/util/rd_intermediate.exe to check what variables are included in your intermediate files, and send the log file to take a look. Thanks.
 
hello, my ed.log,

Based on rd.log, I believe that your intermediate files are correct.

What error messages did you get when you run metgrid.exe?
 
Hello,
my FILE* intermediate files are around 45 MB, but when I run metgrid.exe, the generated met_em files are only 15 KB, and no error appears.
I am using ERA5 pressure-level and single-level data with the Vtable.ECMWF table. The same data worked in WPS 4.3.1, but now it doesn't work for 4.6.
I am attaching metgrid.log.

Your metgrid.log shows that

*** Successful completion of program metgrid.exe ***

I believe that you have successfully run WPS. The file size depends on grid numbers/domain size. GFS is global data, and it is normal that GFS has larger size.
 
The met_em files generated with WPS 4.3.1 are about 150 MB for the third domain, but in WPS 4.6 they are essentially empty — only about 15 kB. Then real.exe, when using these empty met_em files, does not create the wrfbdy file.
 
The message in your metgrid.log is:

*** Successful completion of program metgrid.exe ***

I suppose met_em files should be created successfully. You can do a quick check using ncview...

If your intermediate files are correct, then there is no reason megrid.exe would fail. Furthermore, real.exe will fail if met_em file is not correct.

We don't judge whether a case is successful or not based on file size. We do need to check the content of the files.
 
My met files are empty: Time = UNLIMITED ; // (0 currently). When I attach the same FILE to metgrid.exe from wps 4.3.1, the met files are created correctly. The problem is with metgrid.exe in wps4.6
 
This is weird ...

I just run a quick test case using wps-v4.6.0, and It works just fine.

I still believe this is a data issue. Please double check that you run with correct intermediate files.
