Adding new Stanza groups causes SumB=0 assertion in CalculateStanzaParameters

Reported by: jeroens Owned by: administrator
Priority: normal Milestone: Ecopath 6: build 6.0.7
Component: Ecopath Version:
Severity: major Keywords:


For a yet unexplored reason, SumB is computed as -INF instead of >0 when a new stanza config is added with at least 2 groups

I will see what I can improve on the database end, Joe

This seems to happen when creating the very first stanza configuration in a model. When opening the edit multi-stanza dialog for such a stanza config, values are as follows:

vbK = -1
biomass for first group = NaN
biomass for second group = -9999
Z = -9999
Consumption/biomass = -9999

Clearly something is wrong; maybe you have an idea. The data in the database seems in complicance with other stanza groups in other databases.

Solving this created issues in the Stanza Dialog interface. It now displays the -9999 values (NULL)
