Re: [TRNSYS-users] problem in creating a simple new component

You also have to write the same line in the part where it says (!Do All of the First Timestep Manipulations Here - There Are No Iterations at the Intial Time) after getting the input value and before writting the output value.

Which trnsys version are you using??? code is kind of different to the one created by mine when I export new proformas

Hello everybody

�

I have problem in creating the new component utilising simulation studio skeleton to create new components.

�

Description of new component that I am going to create:

Input, output and parameters:

�

Input: inp

Output: opt

Parameter: par

Equation:

Opt = inp + par

�

After exporting the performa to fortran the codes comes up in VBF6.6B but unfortunately I don�t know where I should add my simple equation in the script.

I Transys manual 1-68 has been mentioned that we have to add our equations instead of highlight question marks in the fortran script. But in the fortran file there is no question mark.

�

The tmf file along with fortran file have been attached and also the fortran script has been mentioned below.

�

I was wondering if you could help to run this simple component.
