Other Hybrido processes, like the creation of the fluidвЂ™s distance field or displacement are not accelerated by your computerвЂ™s OpenCL devices вЂ“ this also applies for the generation of Hybrido secondary elements (splash, foam, mist). Generally, the final influence of the OpenCL device strongly depends on your scene setup and settings and it is not possible to predict the effect on simulation times globally. The real influence of OpenCL can be seen in processes where Hybrido particles are involved: simulations with a high number of particles (compared to the number of cells) will normally perform better than scenes with small вЂњCell sizeвЂќ and low вЂњParticle samplingвЂќ values. Of course, the main reason for OpenCL-supported simulations is to increase simulation speed. standard particles or body dynamics, do not profit from this feature. To mention it again: other simulations, e.g. This is already the entire procedure and once OpenCL is enabled, RealFlow will use the appropriate devices for your Hybrido simulation. вЂњDenseвЂќ will require more memory than the вЂњAdaptiveвЂќ or вЂњSparseвЂќ modes, but it is also significantly faster (20-35%).

The settings here will overwrite your adjustments from the вЂњPreferencesвЂќ, so even if you have activated OpenCL globally, you can turn it off for the currently loaded scene.ДЄnother important step is to activate the Hybrido domain's вЂњDenseвЂќ mode which is perfectly suited and optimised for GPU-based simulations. The second method is to choose whether you want to use OpenCL or not for each scene individually with the previously mentioned вЂњSimulation OptionsвЂќ.

вЂњ GloballyвЂќ means that this feature will always be enabled and you do not have to activate it when you create a new project. The first, is to enable the available OpenCL devices globally under There are two main methods to activate RealFlow OpenCL support.

How to Use RealFlowвЂ™s OpenCL Implementation Even if RealFlow's вЂњSystem information.вЂќ button suggests that your graphic board can be used, there is unfortunately no guarantee that it will contribute to a simulation. There might be cases where GPUs are not taken into account and in this case you will most probably see a slight increase of simulation time вЂ“ typically a few seconds per frame. There is one important note about RealFlow's OpenCL implementation: At the moment, this technology should be considered experimental and it strongly depends on the used hardware, drivers, and operating system. The window which opens contains detailed information about the detected devices and their computation capabilities.

More information about the specifications can be found when you click on the вЂњSystem informationвЂ¦вЂќ button. By default, RealFlow detects these devices automatically and activates their associated checkboxes. RealFlow provides support for CPU-, GPU-based and OpenCL accelerator devices. To check whether your device is supported by RealFlow, please open the вЂњSimulation OptionsвЂќ panel (it can be opened when you click on the little triangle next to the вЂњSimulateвЂќ button), under вЂњHybridoвЂќ you will find a section called вЂњOpenCLвЂќ.

Due to the almost infinite number of hardware configurations, drivers and system specifications it is actually impossible to guarantee that every graphic device can be used for Hybrido simulations. The minimum requirement for GPU support is a graphic device with OpenCL 1.1. One huge advantage of the OpenCL system is that it is platform-independent and available for all major operating systems. Other RealFlow solvers (SPH, HySPH, Caronte and RealWave) are currently not supported and do not provide interfaces to OpenCL. With RealFlow 2013 we added OpenCL support for Hybrido simulations. OpenCL (Open Computing Language) is an interface for non-uniform parallel computing units, e.g.
