[TRNSYS-users] excel question

[David BRADLEY]

Nick,
   There are two ways that you can get parameter information into a 
simulation from an external source; neither one is ideal and neither one 
uses Excel. First is to use Type70; it replaces whatever parameter 
values you specified in the Studio project with the values that it finds 
in a text file (the text file name is specified by Type70). If you can 
write your parameters such as tank volume to a text file then you can 
have Type70 read them in. Second, you can put all of the values into an 
include file. Your include file has to respect TRNSYS input file syntax. 
For example, you'd have to write:

EQUATIONS 1
V_Tank = 0.5

You could then swap in one include file or another (or rewrite the 
include file from Excel using a macro) before you ran TRNSYS.
Best,
  David
