This page provides information on the Thinking Particles Phoenix FD Sample operator.

Overview


The Phoenix FD Sample operator allows you to extract Grid Channel data from the Phoenix FD Simulator. For example,  the Speed channel can be sampled and transferred to a vertex color map for a mesh instance.

Inputs



Time [ time ] – Time at which the TP Sample operator should evaluate. 

On [ bool ] – True if the TP Sample operator should be enabled.

Position [ position ]– [ Required ] World space position at which the Phoenix FD Simulation will be sampled.

 

Outputs


To successfully sample a Phoenix FD Simulation's Grid channel, the respective channel export should be enabled under the Output rollout of the Phoenix FD Simulator.

If the channel is not present, the TP Sample operator will return a value of 0.

You can find more information about the ranges of the grid channels in the Grid Channel Ranges page.

Velocity [ vector ] – Returns the Velocity vector at the sampled Position.

Smoke [ scalar ] – Returns the value of the Smoke channel at the sampled Position.

Temperature [ scalar ] – Returns the value of the Temperature channel at the sampled Position.

Fuel [ scalar ] – Returns the value of the Fuel channel at the sampled Position.

Color [ vector ] – Returns the RGB channel value at the sampled Position.

Viscosity [ scalar ] – Returns the Viscosity channel value at the sampled Position.

Speed [ scalar ] – Returns the Speed channel value at the sampled Position - the Speed represents the magnitude of the Velocity.

 

Parameters


Phoenix Simulator | node – Determines which simulator will be used.
