RealFlow Official Forum

Hi,

I'm a bit of a newbie, learning realflow, working on a hybrido scene which renders fine on my MBP but crashes repeatedly on my Mac Pro:

Processor 3 GHz 8-Core Intel Xeon E5
Memory 16 GB 1867 MHz DDR3 ECC
Graphics AMD FirePro D700 6144 MB
Software OS X 10.9.3 (13D65)

The issue seems to be when it tries to display something visually- command line works fine for Sim on either platform.

In the Mac Pro, if I run command line mode it completes the sim, then update the time line with cache, then if I click anywhere in the timeline it crashes (presumably as it tries to load the picture graphically?)

Or in the Mac Pro if I uncheck command line, it crashes also.

In the MBP it does not crash in either situation.

I have a sneaking suspicion this has to do something with the GPU that's detected in the Mac Pro?

Anyone have any idea why this is happening and/or how to fix it?

Thanks in advance!

Ok I think I found a similar issue here:
http://www.realflowforum.com/viewtopic.php?f=72&t=9800

Can someone from Nextlimit please confirm the issue?

Is this fixed in RF 2014?

Hey,

Have you run the simulation without GPU and it is working?. Anyway, we'll check it out. I'll let you know what it is in short time.

Thanks for reporting!

Hi Luis

Thank you very much for the reply!

BTW side note I really like your youtube video tutorials, they're great

I did uncheck under the Hybrido simulation settings, the box where it says to use GPU but it still crashes either when I run the simulation not in command line mode, or if I try to update the timeline.

Thanks,

James

Hey,

RealFlow 2013 is crashing when trying to paint the particles in viewport. To avoid that, check you have installed the last version of RealFlow, download it again if you are not sure, the last version for mac was released february 3th 2014, and the last thing will be to uncheck the option Use Vertex Buffer Objects from Preferences.

Thanks for your words
