ERROR 10199 - NaN detected in global wq concentration initial conditions

Description

Raised when the global water quality concentration initial condition value (specified via Initial WQ Concentration ==) is NaN when applied. This can occur if the value in the control file could not be parsed as a valid number.

Suggestions

Check the Initial WQ Concentration == line in the control file and ensure a valid numeric value is specified for each water quality constituent being simulated.
