You can use the Liquid Source to emit FLIP particles into Liquid Simulators. It's not a problem to use it for emitting liquid as well, but you have to understand Grid Channel ranges well.
You can emit fluid from geometry or from particles. The fluid can be emitted from the surface, or from the entire volume of emitting geometry. Particles can emit from a spherical shape, or from instanced geometry shapes. Note that the viewport gizmo of the Source does not emit fluid itself - you have to first pick the geometry or particles you would use as emitters in the Source's list.

The main purpose of Texture UVW is to provide dynamic UVW coordinates for texture mapping that follow the simulation. If such simulated texture coordinates are not present for mapping, textures assigned to your simulation will appear static, with the simulated content moving through the image. This undesired behavior is often referred to as 'texture swimming'. In Phoenix such textures can be used for mapping the fire or smoke color and opacity of volumetrics, as well as the color and opacity of meshes. Texture can be also used for displacing volumetrics and meshes. UVW coordinates are generated by simulating an additional Texture UVW Grid Channel which has to be enabled under the Output rollout for the settings below to have any effect. For additional information on the Texture UVW feature, please check the Dynamics roll-out documentation. |

Inherit TexUVW From Geom | texuvw_geom – Sets the UVW Grid Channel value for each cell where fluid is emitted to the UV value of the emission geometry in that cell. As a consequence, for example, modulating the Smoke Color with a texture on the very first frame will produce a render that looks very close to the original geometry, if the same texture was applied to it. When this option is disabled, the TexUVW values will be based on the position of the emission object inside the Simulator. Please Please check the Texture UVW example below.
