Re: [TRNSYS-users] Type 534 invalid floating point operation

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

Jens,
 My guess is that you may need to look at the section of Type534
that reserves space in the global output and storage arrays. Space is
reserved in the OUT() array by setting INFO(6) and then calling TYPECK()
at the start of the simulation. Space is reserved in the global storage
array by calling the SetStorageSize() subroutine. The problems that you
describe sounds like what happens when one component overwrites the
outputs of another.
Kind regards,
 David
