Set time to 0 in dynamic simulations

StPatrick · February 17, 2016, 13:43

Hey,

just started a dynamic Simulation of a room climate concept. Now I want to set the time to Zero by maintaining the results...
Any idea?

Greets, Patrick

You can use:
rpsetvar 'flow-time 0

This sets the flow-time variable to 0s.

Thanks. It works, however the Simulation seems to be different afterwards for some reasons. It might have Change something which i cannot identify.
Is there any possibility to Change it in the menu directly?

rpsetvar is the only way to directly change a built-in variable. With this method, you can be sure that the flow-time variable was the only variable affected. Using a menu, a lot of things can happen under the hood, but not with rpsetvar.
