preview lighting won't change once project created

Hi, I've got the learning edition of RealFlow 2015, with the latest bug fix issued a couple of months ago I've tried to change the lighting settings once a project has been created, such as the time of day and angle of the sun, motion blur and so-on, and it doesn't seem to accept changes once the pr...

Re: SPH plus complex object = infinite simulation time

Aha! Thank you for that point directing my attention to the object. I had ignored the warning message saying there was a possible intersecting object (or words to that effect), as the dfx object was in fact two separate objects that were slightly merged, but not properly. Doing it with another dfx o...

SPH plus complex object = infinite simulation time

Hi, I've got Realflow Learning Edition 2015, latest version, running on Windows 7 ultimate with 8Gb RAM. My focus is on simulating behaviour and measuring results rather than rendering. When I have a bounding box and an emitter, the simulation with about 800,000 standard SPH particles takes about 45...

Re: Drop then Float

That's very similar to what I've been trying to do. From extensive experiments, it appears the only water model that works properly for floating objects is standard SPH. The downside is that it is excruciatingly slow to simulate, and there may be problems with complex objects too.

Re: Floating objects and simulation performance

Ok, have tried Dyverso. Utterly useless for floating objects unfortunately. With Dyverso PBD the object just falls straight through it, and with Dyverso SPH the floating object does float, but behaves as if the devil has got into it, with it spinning wildly and eventually being thrown sideways off t...

Re: Floating objects and simulation performance

Forgot to mention, I do have RealFlow 2015. The frustrating thing is that I have a super-economy processor and motherboard for this computer (AMD 3850 on AM1I) which super-low power consumption, but pretty slow, and a wizzy Nvidia graphics card. The SPH particles are hogging the CPU and taking forev...

Re: Floating objects and simulation performance

Hi, thanks for the suggestion, I'd like to respectfully suggest that you're missing the point though: I know that Realflow is intended more for visual effects, but what I'm actually using it for is simulating real physics, because NextLimit's engineering solution, Xflow, is beyond my price means. Th...

Floating objects and simulation performance

Hi, I've finally got objects to float using ordinary SPH particles, and it appears to work properly compared to Hybrido where it just didn't work at all how it was supposed to. I'm going to simulate the behaviour of a device that floats in the ocean in that I need to find out how it will really beha...

Measuring torque in mechanical device

Hi I tried this message in the python script thread but although I had 77 reads, I got no replies, so I'm trying this one. I have access to Realflow 13 although I'm noob at it. My objective is to be able to measure the power generated by a mechanical device when acted upon by water. Ie, to simulate ...
