Fluid Object Settings

Fluid objects emit fluid into the domain only once. Fluid objects must be Blender mesh objects and must be Manifold in order to work correctly and predictably within the OpenFLIP simulator. If the mesh object is animated, the mesh must not change topology between frames. This means that the mesh vertices are always connected to the same neighbouring vertices.

Parameters

Trigger Mode	The frame offset that the fluid object will be added to the simulation domain. Frame Offset     Trigger the fluid object a frame offset from the first frame of the simulation. Timeline Offset     Trigger the fluid object at a frame in the Blender timeline.
Fluid Velocity Mode	The method in which the initial fluid velocity will be set. Manual     Set the initial fluid velocity vector manually. Target     Set the initial fluid velocity vector towards a target object.
Fluid Velocity	The initial fluid velocity vector (in m/s). This setting is only available if the Fluid Velocity Mode is set to Manual.
Fluid Speed	The initial fluid speed towards the target object (in m/s). This setting is only available if the Fluid Velocity Mode is set to Target.
Target Object	The target object that will be used to calculate the fluid velocity direction. This setting is only available if the Fluid Velocity Mode is set to Target. Notes: Target objects may be located outside of the simulation domain. Empty objects may be used as target objects. If the target object has non-zero size, the fluid velocity will be directed towards the center of the target bounding box.
Export Animated Target	Export the target object mesh as an animated one. This setting is only available if the Fluid Velocity Mode is set to Target. TIP: Animated objects can be slower to export, so use this option only if necessary, such as for armatures or parented objects. Objects with keyframed position/rotation/scale do not require this option to be enabled.
Add Object Velocity to Fluid	Add the object velocity to the initial velocity of the fluid. The object mesh must be rigid (non-deformable) for this option to work correctly.
Object Velocity Influence	Amount of velocity that is added to the fluid. A value of 1.0 is normal, less than 1.0 will dampen the velocity, greater than 1.0 will exaggerate the velocity, negative values will reverse velocity direction. This setting is only available if the Add Object Velocity to Fluid setting is enabled.
Export Animated Mesh	Export the fluid object mesh as an animated one. TIP: Animated objects can be slower to export, so use this option only if necessary, such as for armatures or parented objects. Objects with keyframed position/rotation/scale do not require this option to be enabled.
