Create 'All' Option for Intermediate Results (Results Output Settings)

Status: Under Review

I would like an 'All' option for Intermediate Results in the Fill+Pack solver parameters.  I find it frustrating that solver timesteps are solved but not outputted for results.  As it stands, you either need to:

  • Use the 'Write at constant intervals' option, which will miss timesteps for fine timestepping.
  • Use the 'Write at specific times' option, but this requires us to know when all timesteps will occur before running the analysis, or to assume a very small time interval.

I understand that computing resources will be tied up for results output and file storage, but this option would still be of use to me.

I think the idea is valid, but as you indicated, showing all results has consequences; solver speed, data transfer, disk space, and memory consumption in post processing, post processing speed. etc. So this  could come at a substantial cost.

 

An alternative solution would want to make you aware of could be that you change the default solver behavior for your process to output for instance 50 time steps in filling, packing and cooling and save that as your default solver parameter behavior. Going forward, you would then by default follow your behavior.

Hi Hanno,

 

Thanks for the comment.

 

Just to clarify, using 50 time steps in filling is not always enough for me.  50 outputted time steps mean you get results for approximately 2% volume fill increments.  If you want to zoom in on things like air traps, you sometimes need tighter time steps to visualize the results.

 

An increase in the maximum output during filling to 100-300 time steps would probably eliminate this issue, or an 'All' option would default to the solver settings.  The current workaround requires the user to use the write at specific times option, guessing at a small enough time step.  It's really just a small annoyance.
