Hello！ I’m learning to run CMAQ5.3.1 .The IC/BC I made through WACCM data,The time step I set is 6h,here comes errors when I run cctm.csh,errors display as follows,  
SA\_ACONC\_1 :/home/u120220900721/CMAQ5.3/CMAQ\_Project/data/STE202206/cctm/CN9NC\_239X213/CCTM\_SA\_ACONC\_v531\_intel\_STE202206\_20220602.nc

```
 >>--->> WARNING in subroutine OPEN3
 File not available.

 Could not open SA_ACONC_1 file for update - try to open new

 Timestep written to SA_ACONC_1 for date and time 2022153:000000
  =--> Data Output completed... 0.9 seconds

 ERROR: Incorrect Interpolation in 3-D Generic Interpolation for variable:
 DENSA_J

```

I suspect there’s something wrong with the mcip output files due to the varible DENSA\_J  
Thanks
