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

Mon Jul 12 06:43:33 PDT 2010

Dear Jaime

Many thanks for your reply

I have implemented your advices.

1- I added opt=ipt+par just after “ !Sample Code: OUT1=IN1+PAR1”  line
without “ ! ”.

 2- I wrote the same after (!Do All of the First Timestep Manipulations Here
- There Are No Iterations at the Intial Time)

But unfortunately there was an error in compiling the script which is :

--------------------Configuration: Type211Lib - Win32
Release--------------------

Compiling Fortran...

C:\Trnsys17\MyProjects\type 211\type211.for

C:\Trnsys17\MyProjects\type 211\type211.for(122) : Error: This name does not
have a type, and must have an explicit type.   [OPT]

      opt=inp+par

------^

Error executing df.exe.

type211.dll - 1 error(s), 0 warning(s)

----------------------------------------------------------------------------
----------

It is Trnsys 17 and CVF6.6B. 

I was wondering if I could have your further suggestions.

Regards

Mehdi Shahrestani

you have writen it there, but it is commented. You have to uncomment the
line where it says

!Sample Code: OUT1=IN1+PAR1

so that it would be:

OUT1=IN1+PAR1

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.

! This TRNSYS component skeleton was generated from the TRNSYS studio based
on the user-supplied parameters, inputs,

carefully and add the content to transform

should be the average value over the timestep

! and not the value at the end of the timestep; although in many models
these are exactly the same values.  Refer to
