problem with nudging and fdda

This post was from a previous version of the WRF&MPAS-A Support Forum. New replies have been disabled and if you have follow up questions related to this post, then please start a new thread from the forum home page.

Hello, I'm running wrf using nudging. When I add fdda section in the namelist.input, then I only have one single time output in each wrfout file, and there is only wrffdda_d01, but no wrffdda02 for d02, but in fact I use nest running with d01 & d02, also, I set frames_per_outfile = 1000, 1000, But I don't have the dimension 'time' in my wrfout files. What should I do with that?
But if I remove fdda section, the dimension 'time' in my wrfout files will be normal. Could you please tell me how to do that?

I believe that I have answered your question somewhere else. Please don't post the same question to in different places.
