Error when FreqUnits set to never in InitialState stream

[xylar]

I am trying to do a restart run. When I have:

    InitialState:
      UsePointerFile: false
      Filename: init.nc
      Mode: read
      Precision: double
      Freq: 1
      FreqUnits: never
      UseStartEnd: false
      Contents:
      - State
      - Tracers

I am seeing:

$ cat omega.log

[* info] [TimeMgr.cpp:1218] Omega using calendar type: No Leap
[* warning] [IOStream.cpp:527] Stream InitialState has IO frequency of never and will be skipped

This is on Chrysalis (with Intel). My directory is:

I'm using the latest develop.

@philipwjones, I'm afraid this might be another one for you.

[xylar]

A fix for this is needed for E3SM-Project/polaris#251

[philipwjones]

@xylar Streams is the gift that keeps on giving...this is actually the same base issue as the missing RestartRead since we don't bother creating the stream if the frequency is never and then Init tries to read the stream later. I'm working on a mod that should fix both. Sorry for the ongoing issues.

@philipwjones, absolutely no worries. I'm having a lot of fun figuring out how to make Polaris work with Omega. I'm making lots of mistakes along the way and then very occasionally discovering things that are actually bugs and not me messing things up. 😛
