newbie questions

Phoenix General
1

Hi All,

I’m trying my hand at a beach waves sim and have a few questions when it comes to rendering it.

I have simmed 1000 frames and if I only need the last 300 frames I assume I can delete the .aur files to save disk space? my sim is 600mb per frame.
If I want motion blur, do I need the velocity channel on the output grid?

In general what can I do to save disk space?

Is there any advantage to using vrayvolumegrid or can i just make sure all slaves have phoenixFD installed?

Finally we got a new i9 7960x machine with 128gb ram and 2 samsung pro ssd drives for the purpose of doing phoenixFD sims. I’m getting 3M vox/s currently. Does that sound about right? Is there anything I should do or check to make sure everything is going as quickly as possible? Maybe turn off hyperthreading? I’m not sure i really want to get into overclocking but maybe i should?

thanks all!

1. Yes, you can safely delete the unneeded files.
2. Yes, you need Simulator → Output → Velocity grid channel exported for motion blur
3. You can try reducing the Output → Storage Quality but this could cause artifacts. Please check the screenshots here: https://docs.chaosgroup.com/display/…/Liquid+Output
4. As far as I know, the rendered result using volumeGrid vs Phoenix FD simulator should be identical.

I can’t give you an informed answer on the hardware questions. Hopefully one of the devs can chime in.

edit; Completely slipped my mind - we have an entire thread on the topic of hardware: Recommended Simulation hardware - General - Chaos Forum

Hope that helps.
