'Max temperature must be(...)' Error

Hello,

I need some help, I designed a room for CFD analisys, but when I click the CFD tab, it shows me the error in the attached picture.
I don't think I've changed anything that could lead to this error, but if you're kind enough please do take a look at my .dsb file (also attached).

Thank you!

Hi,

The problem with your model is to do with the supply diffuser settings. The limits for the supply diffuser discharge angles should be -80 to +80 degrees but due to a bug in the interface, it is possible to enter a range of between -90 and +90 degrees. You have set the discharge angle to -90 degrees along the local Y-axis and this is creating invalid data in the calculations. If you change the Y-discharge angle to -80, delete your existing CFD project and create a new one, you should then find that you can conduct the calculation without a problem.

If you want the diffuser to discharge in the plane of the ceiling, you could add a supply diffuser to the adjacent wall or to the surface of a component block, positioned adjacent to the ceiling - see attached images.

Regards,

Steve
