ERROR 10251 - MMM units system not supported for mass balance outputs. Exiting.

Description

Raised when mass balance output is requested alongside a water quality simulation that uses a units system other than mg/L (milligrams per litre). Mass balance output currently only supports water quality models using mg/L units.

Suggestions

Remove the mass balance output block, or configure the water quality model to use mg/L units. If mass balance output is essential with a different units system, contact support@tuflow.com.
