Re: DOMAIN error

[David Bradley <bradley@xxxxxxxxxxxx>]

Ulrika,
  I believe that you can also get this error if TRNSYS tries to take the 
log of a negative number, not just from an NaN. The solution is the same 
unfortunately, if you have a Fortran compiler, you can step through and 
have it indicate where the problem is occurring. If not, you should 
probably contact your distributor directly for help tracking it.
Kind regards,
  David
