KVS value et to zero

The error message:

This error may occur when executing the ‘optimise system components’-calculation step.

Open

Meaning:

The KVS value locked by the user has been set to zero. This would mean that the pressure drop over the valve would be infinite, which the solver can’t use to calculate.

Open

How to solve this error:

set either the KVS-value to the correct value, or allow Hysopt to calculate the correct value.

If you require a valve to be permanently closed, use the base circuit “pipe end” which you can find under header configuration.
