Phoenix FD 2 crashing when quality/res is raised, not sure why.

[Deflaminis]

Hello, I was working on trying to setup a tank shooting + dust based on some interesting posts I found on youtube, and I'm finding that phoenix is timing out or simply crashing after about 10-20 frames. If I check my RAM it's not capped out or anything, but for some reason I just can't get this simulation to go. It works if I reduce the res or lower the quality, but according to the tut this was the setting used. I was mainly doing it for a comparison.

Tried to figure it out but I don't know where the problem lies. I'm not overly concerned about the time per frame, but the crashing is making it moot. I'm certain I did something wrong in here, but I'm not sure what. I've attached the scene, it's very simple just a test really. I've tried everything from remaking the entire scene to using the max memory %, but nothing is helping. (Sim says it only needs 4GB ram and I have 32). Again, I'm sure I did something wrong but I can't figure out what it might be that causes it to choke. Any help is greatly appreciated.

I tried the things listed here: http://forums.chaosgroup.com/showthr...-million-cells

But no luck. I'm nowhere near that many cells, but still crashing on frame 10 or so.

EDIT: So I disabled the active grid and it does seem to be working now. Even with max memory at 50% for me the scene would crash around frame 10-20, usually 15.

Hello, we are having a look at the scene, and yes, it's related to the adaptive grid, and it looks like the memory does not suffice, but we're still investigating. Looks like at the moment the shell leaves the grid, it causes a huge expansion. If you don't want to disable the adaptive grid completely, you could put an adaptation limit at least on that side of the grid, or use preallocation with the adaptive grid - this way when the grid increases, there won't be a peak that doubles the used memory at the moment when both the old grid and the new grid data exist simultaneously.

Wow thank you for the reply! I will look further into putting a limit on it. I know you guys are busy so I don't want to take up more of your time, this gives me what I need to try other things. Really appreciate it. I actually learned a few things i could do differently by watching your carpet bomb tutorial. Not sure how I missed those for so long but they have helped tremendously for my understanding on phoenix. Thanks again.

Oh, thank YOU for the report! It shouldn't crash under any circumstances, so now it's handled properly and one can resume his work. If you have any other issues, please share. There are many things to be improved and although we have a long list, there still could be issues that we haven't seen.
