SMS:Extract Particle Subset

This command writes a portion of a particle set to a new a particle file. This portion may be a subset of the timesteps for the particle solution, a subset of the particles, or both. To get to this command, right-click on a particle set and choose Extract subset (times/particles).

The required information for this command includes:

• The filename to write the particle subset to.
• The first and last time steps that define the range of time the user wants export.
• Whether to write every time step, every other time step, every third time step, etc.

A user may define a subset of the particles to export by setting up filters (see PTM Particle Filters). For example, a user may decide to only write particles with a specific range of grain size, or particles from a specific source.

The extracted particle set will have the same datasets that exist in the original particle set.
