[TRNSYS-users] Query about Type 50f

[David BRADLEY]

Sanjeev Jakhar,
   This was an error in the Type50 proformas that was resolved some time 
ago. It would probably be a good idea to contact the primary license 
holder at your institution and make sure that you have the most up to 
date TRNSYS version.

   It is possible to fix the problem yourself in this case. To do so:
1. open the Type50 proforma by double clicking on it from the Direct 
Access menu in the Studio.
2. Change to the "variables" tab and click the "variables (parmaeter, 
inputs, outputs, derivatives)" button at the top of the page.
3. filter on "parameters" by clicking the parameters tab
4. select the third parameter by clicking on the number "3" then click 
the "modify" on the right.
5. set the "minimum" field to 0 and the "maximum field to +Inf
6. click ok
7. save the modified proforma.

once you have modified a proforma, it is necessary to right-click on 
that Type in your project(s) and select "replace" from the context menu, 
then browse to locate the proforma in the direct access structure.

kind regards,
  David
