[TRNSYS-users] TRNOPT reporting weird error when using parametric runs

[David BRADLEY]

Amin,

  Make sure that all of the path names to external files in your project 
are absolute (ie c:\Trnsys18\MyProjects\ProjectX\myBuilding.b18). 
TRNOpt/GenOpt makes a copy of your input file, adds in the present 
values of your variables and runs it from its own location. If you have 
relative paths (ie .\MyProjects\ProjectX\myBuilding.b18) then those 
files don't exist at the specified location once the input file has been 
moved.

kind regards,

  David
