[TRNSYS-users] Flow mixers and diverters

Dear Rémi,

I am attaching in a separate email a test project that I created with 
the components that you described.  The project worked fine in my 
computer.  Please let me know if it works.  For the mixing processes I 
used Type11h, and for the diverter I used Type11f.
Is it possible that we are using different component modes?
Best regards,
