Re: Slow/unstable Sim

Questions: What is the cell size setting for this object? What is the task manager saying about RAM use during simulation ?

Re: Slow/unstable Sim

Hi RF is probably calculating something that is completely unnecessary for this sim. I assume, the poser figure just acts as an obstacle and moving around? In this case you can disable object simulation in the simulation preferences. You can also test, which element of the sim is responsible for the...

Re: Dyverso Crashes when using OpenCL-GPU or CUDA

A bit of curiosity, how many particles were on the scene when the crash happened?


Sorry, I don't know exactly because I have deleted that project already, but it was more than 3 millions with that card with 4GB RAM.

Re: nice demonstration of granular solver

I wonder if that kind of soil is achievable ? Yes, that is possible. It might need two different domains interacting, one for the finer grains and the other one for the chunks. At the beginning I had problems to get these bigger pieces to remain intact, but the blog post by Tsn about the effect of ...

Re: Object Cell size vs Hybrido cell size

[quote]I'm calculating foam now , from precalculated(cached) hybrido , is that right workflow ? [quote] Yes, that is the best workflow. Tutorials: Unfortunately, the days of numerous Youtube tutorials is more or less over. Also consider that RealFlow was a smaller and less expensive tool in the firs...

nice demonstration of granular solver

I liked a lot this video by Fernando J. Casielles using the new Dyverso granular solver. He also shows a little bit about the techniques he used and which render engine.

Re: Object Cell size vs Hybrido cell size

Hi and welcome 1) I understand the manual in this way: if the objects cell size is smaller than the hybrido domain cell size, then the calculation uses the domain size. So, there is not really a big opportunity to save time and memory here. Maybe it is better to have the default smaller size in the ...

Re: Cant make liquid pour out due to gravity from a half open tomato. It always goes through the geometry

Should I simulate in high fps then playback lower


Yes, that sounds good. In this way you don't alter the properties of the liquid. Otherwise you could have increased drag daemon to slow down the liquid, and also increase its density because daemons work less strong on heavy liquids.

Re: Cant make liquid pour out due to gravity from a half open tomato. It always goes through the geometry

Hi there are several possible reasons why it does not yet work as intended. It is not easy to tell without seeing the project, but I could imagine, that the tomato object is in a collision mode that does not allow the particles to interact with it or completely intersects with it. A fill object as l...

Re: Dyverso Crashes when using OpenCL-GPU or CUDA

Today I had an unexpected exit of RF10 in terminal mode with a scene using Dyverso (SPH-particles, high viscosity) and Cuda. At least we can say that the error message made clear what the primary issue at this point was: >14:37:31: ================ Frame finished ================ >14:37:31: ========...
