Re: [TRNSYS-users] More sampling points for bi-axial IAM for Type 71

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

Lotta,
You are correct that there is no limitation in DynamicData. I also had a
look at the Type71 code and there is nothing in there preventing you
from having more than 10 values of IAM. The restriction is in the Type71
proforma itself. What you will need to do is modify the Type71 proforma
to increase the maximum value allowed for that particular parameter,
save the change, then perform an Edit: Replace on the component that is
in your project. Modifications made to proformas are not automatically
made to projects that contain those proformas.
Kind regards,
David
