Re: [TRNSYS-users] Outside temperature iteration

[David BRADLEY <d.bradley@tess-inc.com>]

Dr. Sarmouk,

  I would recommend finding surface 443 in TRNBuild and then looking at its external convection coefficient. If the external convection coefficient is set to be variable then as a test, set it back to a constant and see if the error goes away. You can also look at whether the wall is very highly thermally conductive and whether it has a particularly high solar absorptance on its outside surface.

kind regards,

 David

Dear Trnsys users,

I am facing a problem with my current model. the simulation stops and the following error message is displayed :

    Generated by Unit     :    56
    Generated by Type     :    56
    Message               : Outside temperature iteration of external surface (SURF=  443) of airnode    3 at time  5841.00 caused error!

Any recommendations?

Dr.SARMOUK
