During my analysis computation after 11 simulated days I stuck on this error message:

askid: 0 hostname: gv0147

-------------- FATAL CALLED ---------------

normalize_basetime: denominator of seconds cannot be negative

-------------------------------------------

application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

askid: 0 hostname: gv0147

-------------- FATAL CALLED ---------------

normalize_basetime: denominator of seconds cannot be negative

-------------------------------------------

application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

My intuition says that it is a matter of adaptive time step. But my calendar says that I want to use the adaptive time step. Did You have similar problem?

Here are my settings:

- modified the model decomposition to use more processors

- activated the Gravity Wave Drag for first and second domain (why --runinfo show that I enable it for all domains??)
