[TRNSYS-users] How to accelerate running .dck files from the command line

[David BRADLEY]

Joe,

  There isn't really a way to avoid all that initialization. It is the 
kernel reading and checking the input file and then getting all of the 
internal data structures set up so that they can be accessed by the Types.

kind regards,

  David
