Re: [TRNSYS-users] Type 43 external file format and active layer activation



Chris,

1) I am trying find the input file format required for the Type 43a
(Part Load Performance).  I can't find any documentation that describes
this nor have I found an example.  Can someone point me in the right
direction?
Type43 uses the standard TRNSYS external file format for one-dimensional data. If you check the Type43 section in the Mathematical Reference manual, it will point you to the section in the Programmer's Guide that describes the format for files that are read by the "DynamicData" subroutine (trnsys16) or by the "InterpolateData" routine (trnsys17)
2) I want to create an active layer type but the "Active Layer" radio
button in the Layer Type Manager is greyed out.  How do I make this
available?
Because the active layer model in Type56 is semi-empirical, it imposes some requirements on the layers that surround the active layer itself (usually concrete). For example, the minimum pipe spacing in your active layer depends on the thickness of the adjacent massive layers. As a result, TRNBuild allows you to define an active layer only in the wall manger when you have a massive layer selected such that it can check to make sure that its requirements are being met.

Best,
david
