Flow: Unified Physics - Preferences

Last modified: 17 December 2024

The Flow Unified Physics plugin preferences/setup panel is shown below:

  • Add Item: Add an item to the simulation

  • Edit List: Allows you to choose which items are included in a simulation.

  • **Make New Set:**This allows you to make a new set of simulation items. You can have a simulation that acts on multiple sets.

  • Add Set: This allows you to add your sets to a simulation.

  • Mode: Allows you to either Preview or Bake the simulation. Prior to rendering, the simulation should be baked once you are satisfied with the results.

  • Time Steps: Allows you to define the subframe steps (i.e., the times that the simulation is calculated). This allows finer simulations at the expense of increased calculation time.

  • Simulation: Allows you to Run, Pause of Reset the simulation.

  • Substeps - The number of substeps (i.e. the frame rate is divided by the number of substeps to determine the number of simulation calculations done per frame) per frame where the simulation is calculation

  • Iterations - The number of iterations calculated for each substep.

  • Particle size - Sets the size of the LW Flow particles

  • Collision distance - Distance between particles for collision detection

  • Adhesion - How particles 'stick' to each other

  • Dynamic friction - When particles collide do they steal energy from each other

  • Relaxation mode - There are two options. Either Local which means the simulation is relaxed at a Local coordinate level, or Global which considers world coordinates. Choosing world coordinates will result in a longer relaxation time.

  • Relax Factor - The Relaxation factor is the time it takes for a particle to speed up from one velocity to another.

  • More simulation options - see below.
