Environmental Conditions -- Can't use a new record

[Stephen LeSourd]

I am running Version 7.8.77 of Therm.  Whenever I try to create and use a new exterior condition other than NFRC 100-2010, which is the default, I get the error msg, "Warning: The maximum number of meshing iterations reached before the error target was reached."

Is it possible to create a new exterior condition in this version of Therm?  Is there a setting I need to change?

I don't think this has to do with the environmental conditions. It sounds like your model is too complex and THERM can't mesh it as a result. 

You might try to simplify it. 

If you provide the file, I can take a look at it today.

Hi Stephen,

Which model type did you choose?

Try to use the 'Simplified'.

Kind regards,

Zugur
