[TRNSYS-users] Unknown Unit Number + negative flow rate errors

[Currie, Sam R]

Hi Damien,

The first error at the beginning of the simulation is related to a Type62 component; the unit 24 refers to the order of the components in your simulation. Check your control cards to confirm this. 

As to your second error, it's difficult to tell what's going on from the snapshot. Check the lst file, it should give you more details on the errors you are getting. If you're model isn't reaching convergence as often as you indicated then it may be that TRNSYS has reached the maximum number of warnings or non-fatal errors after 1578 time steps and forced the simulation to exit. If you can't find the error from the lst file then you could try turning debug mode on (it's in the control cards menu) then rerun the simulation and check the lst file again.

Hope that helps,
