Re: [TRNSYS-users] Editing an existing component of a model

["Diego A. Arias" <daarias@wisc.edu>]

Dear Emmanuel,

My recommendation would be to start with the guide found in 'Volume 1 - 
Getting started', section 1.9.  It takes you through how to create a new 
component from scratch and then how to create a new dll.  The general 
steps on this guide are:
- Create a basic proforma in the Studio.
- Export the information as Fortran.
- The Studio creates the workspace for Compaq Visual Fortran. You can 
complete the Fortran code in this workspace.

If you want to modify an existing standard component, I would recommend 
that you copy it and paste it as a new component, with a new number.  By 
doing this, the component will be compiled into a new .dll file that 
will be located in the Userlib directory.  In addition, you will have 
the original component to compare with.  You can use the workspace that 
is created by the Studio, and replace the fortran file with the copy of 
the component that you want to compile. 

After you do the example in the Volume 1, I would recommend using Volume 
8 - Programmer's Guide for additional information about compiling your 
components.

I will be happy to help you as you work on this topic.
Best regards,

Diego
