Why do I get a Validation Error: Inconsistent outside directions - check adjacent walls?
A wall panel has an inside and an outside face to allow the appropriate internal and external coefficients to be defined.
Home ribbon > Settings allows you to define the colours.
You can also show the element direction arrow via the Scene Content > Wall Panel.
The normal wall arrow points to the outside.
Review your model to see if any wall items are inconsistent. i.e. you cannot have an outside wall touching an inside wall as shown below.
Use the Edit ribbon > Reverse command and click on a wall panel to toggle it between inside and outside face to ensure that all the wall faces are consistent.
Use the Load ribbon > Update Zones command to update the information for the edited wall panels above.
Repeat as necessary until Validation and the Wind Model are up to date.
