Simulation Window

The frame number that is currently being simulated. All frames before that have already been saved to the cached and can be rendered in the editor or to the picture viewer.

Time that has elapsed since this simulation run started.

An estimate of the time remaining to finish the simulation run based on the elapsed time and the remaining number of frames. It does not consider the velocities of the fluid, which have a large impact on simulation time. Therefore, if velocities vary a lot during the course of a simulation, this estimate may change a lot.

Shows the current resolution of the adaptive container.

The amount of working memory occupied by the simulation core for processing.

The size of the simulation cache on disk.

If you have supported GPUs, this drop-down box will let you select which one to use. See GPU Simulation for more details about fluid simulation on GPUs.

If "Use CPUs" is selected, all available CPU cores will be used instead.

Let's TurbulenceFD automatically trigger a render after the simulation has finished. This is identical to choosing "Render to Picture Viewer" from CINEMA's Render menu.

Remember to setup the render settings correctly before leaving the workstation. Also, make sure that the destination file(s) do not already exist. Cinema will pop up a dialog asking whether to overwrite the existing files, waiting for your answer instead of rendering.

Update the time-line of the editor as the simulation progresses. This can be used to watch the simulation run using the fast slice-of-volume display. Note that the editor preview will also slow down the simulation somewhat.

Simulate the fluids in this container from the beginning of the selected frame range (see Simulation/Timing/Frame Range).

Stop the simulation. It will finish simulating the current frame in order to allow continuing the simulation later.

The button will change to "Abort". Click it again if you want to abort immediately and don't need to continue the simulation later.

Continue a simulation after the last simulation state. This last state is always saved when the simulation stops. Be it because you click the Stop button or because all frames from the selected range have been simulated. Therefore this also allows you to add more frames at the end of the range.

Post-process a simulation to increase the resolution and add more detail. A new cache directory will be created using the name of the current cache with the word "upres" appended. You can switch back to the previous cache using the Container/Simulation Caches list.

See the Simulation/Up-Res'ing tab for more options.

This post-process is faster than simulating at the high resolution in the first place. It will also retain the shape of the lores simulation and only add small detail that couldn't be resolved on the lores grid before.
