Simulation Presets... | A_LoadRenderPreset – Displays a drop-down menu to either load or save .tpr or .slog files, which hold settings for this simulation.

StartFrame
StartFrame
Start Frame | startframe – Explicitly sets the Start frame of the Simulation. This can also be a negative number. Only available when Timeline (Start Frame) is disabled.

...

Timeline | parmName - When enabled, the Simulation will run to the end of the Timeline. 

Render On Each Sim Frame | rend_sim_frame – During simulation, after each new frame is simulated, this option will start a render with your currently assigned production renderer and with the render settings you have dialed in your Render Setup 3ds Max dialog. You can use this when you leave a long simulation overnight, so you will have a ready rendered sequence when you come back to check on it, even if the entire simulation did not have time to finish. If you are doing test iterations and you don't need your fire/smoke to be rendered with production quality, you could enable the GPU Preview extended viewport and use the Save Images During Sim option instead. When doing test iterations on your simulation setup, you can also speed up the simulation by enabling Cacheless Simulation from the Output rollout. Another alternative is to automatically start a sequence render after the entire simulation has finished by adding a 'max quick render' command under the OnSimulationEnd() callback of the Use Script option below.

NUMA stands for Non-Uniform Memory Access. It can be used to restrict the threads used for simulation based on the physical CPUs available on the system (in a multiprocessor system). In this way, better memory access can be achieved when multiple simulations are run on the same machine.

This area displays information on the current simulation. Any data from channels that have been loaded into the simulator are shown. This includes the minimum and maximum ranges for each channel. Check the Grid Channel Ranges and Particle Channel Ranges pages for more information.
