Heater not working

[Princerivo]

Hi,
For some reason when I am attaching a heater for my model, the program is not responding at all. I am using the last version of the program. Any thoughts on that is appreciated.

Hi Daniel,
Thanks for your kind response. I use Windows 11 and DWSIM version 8.6.5.

Please see attached...

You had a loop around the heater and needed to add a recycle block, check the attached file.

Many thanks for the quick response, very much appreciated. But could I ask is it a must for any loop to have the recycle block?

yes, it is. DWSIM doesn't detect these tear streams automatically.

Thanks alot...
