[TRNSYS-users] Internal gain routine using view factors

[Laurent Georges]

Dear  TRNSYS-users,

In TRNSYS, I try to distribute the internal gains of a heat source between the different walls of a zone as a function of the view factors (i.e. not using the standard approach based on area-weighted average). TRNSYS 17 allows to do that  by defining the "geo position" of the internal gain source: the view factor routine of TRNSYS should compute subsequently the view factors from this point location. Even though the view factors are computed properly by TRNSYS, the TRNSYS execution crashes with the following message : "Subscript #1 of the array ATOFGPOS has value 3 which is greater than the upper bound of 2". Maybe, there is other TNRSYS users who have experience with the "detailed" definition of the gains? With the same conclusions?

In advance, thank you,
Best regards,
Laurent Georges
