Any tips on reducing memory footprint when rendering? My scene is a little odd with regard to memory. I will see one frame render with about 6Gigs, and the next needs 21Gigs. These are successive frames in an explosion. There is not much of a visual difference between the frames. Though I am am usin…

The adaptive grid algorithm is not perfect and it reacts on spikes in the velocity. In the nightlies, this algorithm was changed a bit, and more precise one is used. It improves the problem somewhat. If you are not using a recent build, I will recommend you to try a nightly and see if this helps yo…

6 to 21 gigs is too big difference, it’s strange for frames that are almost equal. one possible reason can be the interpolation of the frames, i will take a look.

Hi Ivo, I am having a similar problem but not with memory but with the size of simulation files. I have modified the submarine sample file and the simulation files spike from 16mb up to 2.1gb! I have attached a screen grab of part of the simulation output files to show the file sizes [Capture.J…

very interesting! there is an option for backup interval, that automatically includes the velocity channel once per given time, but this cant be the case, too big difference in the size. can you compare the content of the frame 188 and 187 ? or better make screenshot of the input panel when these …

the disk is full? i noticed when there is no enough disk space, there are small aur files that are not renderable

That is it! I was saving the files to my SSD but they got too big!

I will try one of the recent nightlies… This may actually be the issue. I think many of the render nodes have a nightly build from a week or two ago, while others have the release. My files are so big presumably because they are pretty detailed. They also stretch out over a large area. I do not hav…

Was out of town on location the past few weeks. But I got back to it. I tried the Aug 9 nighlty build.. Still varies between about 5 gigs to up to 24 gigs per frame when rendering. No time to re-simulate now, though.

can you share the scene and if possible two cache files with big difference in the memory consumption?

Ivo,
If I render at frames 186 or 188 nothing renders but 187 renders as it should.
The backup interval is -1
Attached is a better list of the .aur files
