Re: [TRNSYS-users] An integral problem in trnsys

Thanks for the suggestion, I solved this using a combination of Type150 and equation for integration.


Best regards,

Aoye

I think that you could accomplish this by creating a Type55 for each of the individual integration periods that you want, then combine the results together using an equation.

Dear every users,


I want to achieve integration of different time intervals through type24 or type55 of trnsys.

For example, I now have a model with time step = 1hr and simulation time = 24hr

I want to achieve intergration from
0-1 hr, then reset the value
2-5 hr, then reset the value
6-10 hr, then reset the value
11-12 hr, then reset the value

13-24 hr

This example can be shown in following figure:


Can integral and value reset in this way be achieved in TRNSYS? If it doesn't work, I'm going to use a combination of python and trnsys.


Best Regards,

SONG Aoye
