In this tab, you can control what fields the solver will output and provide various settings to control the resolution and compression.
You can choose to output simulation particles, fields as VDBs, and a visualizer for the sparse data structure for debugging purposes.
Particles always get their positions set when being output. However, you can choose whether or not the velocity, temperature, color, and viscosity attributes are output.
For color you can choose if you what the particle attribute output or if you want color computed from particle velocity. By default it is set to visualize velocity.
You can choose what specific fields get output. Choosing fewer fields will improve the speed of the simulation.
<aside> 💡
In Paradigm most of the fields are for visualizing various internal data rather than being used for anything useful at render time.

You can choose to output some fields at a lower resolution. Sometimes you may not need a full resolution velocity field for rendering. The filter will determine how to downsample a lower resolution grid. Index will skip voxels and write out values at intervals, average will average out a group of voxels to assign to a lower resolution grid.
Deactivate Empty Voxels will not output any voxel that has a value below the simulation threshold value.
16 Bit Write To Disk will compress the volume when it is written out to a file. This will help save on disk space usage without losing much quality if anything. This also tells the GPU to copy from device to host as 16-bit float values.
If you don't need to see the field in the viewport you can mark it as invisible or use one of the other visualization modes.
