Thank you very much. I really appreciate it.

I would imagine so.

Does this mean that the data will be saved at the end of each second until the total time reaches from 0 to 99 sec and then the data starts saving at increments of 0.001 seconds from 99 to 100 sec?

To do so:

(1) select "specified times" (see http://grab.by/2ZuP ). This way it will only save the data points specified in (2)

(2) you can have two stepping period to save even less steps, and concentrate on the last steps. see http://grab.by/2Zv0

Hello,

I am planning to run a time-dependent simulation using the multi-physics module and was wondering if there is a way to save the data file only during the last time step of the simulation.

When I ran the simulation for 100 seconds after choosing free time step option, comsol saved the solution at so many different time points starting from 0 to 100 sec. I now have a comsol file that has solution data saved at atleast 10-20 time points within each second which resulted in a huge data file (~ 7 GB). If I increase the mesh size, then comsol is not even progressing until the end because the file exceeded the storage limit size in the /tmp directory.

I only want to save the solution let's say during the last time step only (i.e. from 99 sec - 100 sec) but want the solution to progress from 0 sec - 100 sec.

How can I define this setting?

Thanks.
