About using Output Intervals

Post by Matthew »

Hello everyone,

I have a question about using Output Intervals. Say, if I have a simulation with

Timestep Intervals(2) = 180
Timestep Sizes(2) = 10

and I want the output for every 100 simulation time. How can I put this into the Output Intervals? I am slightly confuse on how to use Output Intervals.

Thank you for your help.

Regards,
Jamil

Hi

If the size of Timestep Intervals is set to be two you should have two values, e.g.

Code: Select all

Timestep Intervals(2) = 80 200
Timestep Sizes(2) = 1.0 0.5
Now if for this you would like to save only the every 2nd step of the shorter timesteps you would say

Code: Select all

Output Intervals(2) = 0 2
resulting to 100 files being saved.

Thanks Peter,

From your example, is that means during the first 80 timestep interval, there is no output? And, the next 200 timestep interval, the output is saved every 2 timestep sizes of 0.5?

Thanks again,

Jamil

This discussion and viewtopic.php?f=3&t=4267&p=16727&hilit= ... 21f#p16727 are very useful in case of simulation where number of output intervals is very high and can help us in saving hard disk space.
