Re: [TRNSYS-users] Unit Mismatch



Stefan,
 It depends a bit on how you are converting your units. If you are writing a block of equations to convert units then equations have no units by default. You can assign units to an equation by using the 3-letter codes as in:

mDot = 45 {MF1}

the three letter code MF1 indicates a mass flow rate in kg/h.

 If you have checked your simulation and all the connections have units that match one another then you can ignore the warning. It may be that some of the Types you are using are not setting their own three letter input and output unit codes.
best,
 David

Hey together,
i use a unit conversion routine in my projects and allways get Unit mismatch warnings when i watch the listfile after a simulation. Ive checked it again and again but for me it seems to be all correct.
Then ive watched some Trnsys-examples with an Unit-Conversion Routine included and found similar warnings after a Simulation.
Is there a general Problem with the Routine or do i get something totally wrong?


Best regards

Stefan
