Bi-facial Tracker system

[Nurlan]

Hello Everyone,

I am trying to do a simulation and for the Tracking tilted or horiz- N-S axis and i need to use Bi-facial modul too, however, i faced with a error by the name of '' You can only define Bi-facial systems with fixed planes''. I am using PVsyst V6.66 version and i don't have the option of ''use unlimited trackers 2D-model to choose. Anyone knows how to solve or any alternatives?

Thank you in advance.
