The domain’s basic properties can be changed here.
Simulation
The first entry is used to specify how a node contributes to a scene. The default option is “Active” and tells RealFlow that the currently selected node will be considered during simulation. “Inactive” disables it and the node is greyed out. “Cache” is of special importance, because with this method it is possible to read already simulated data from disk and use them in a new simulation pass. The cached item will not be affected by forces or other nodes anymore. On the other hand, a cached node is still able to influence other bodies. In the "Nodes" panel, cached nodes are displayed with a yellow font.

Please bear in mind that this parameter only influences the position of the domain's viewport symbol. The domain itself is placed and scaled by the Hybrido solver. The plane's position is evaluated by the “Open boundary” function of the “Hybrido Mesh” node. "Position" values are given in metres [ m m].
Rotation
In combination with Hybrido domains, this parameter has absolutely no effect. It is also not possible to rotate the viewport representation, because the plane you can see there is used for the projection of the displacement, velocity and vorticity maps. "Rotation" values are given in degrees [deg].
...
The final size and position of the Hybrido domain is determined automatically by the solver. “Scale” will only change the domain's symbol in the viewport. Please note that this parameter has no influence on the domain's cell size. "Scale" values are given in metres [ m m].
Shear
With this parameter it is possible to create a spatial distortion of a node. Hybrido domains are not affected by “Shear”. "Shear" values are given in metres [ m m].
Parent to
Nodes can be bounded to other objects, forcing them to follow their motions and rotations. This function cannot be used with Hybrido domains.
