Particle Insertion

Overview

Particle Insertion is a section in the PTM input that insertion of particles in water bodies over time. The PTM can insert multiple sets of particles.

PARTICLE_INSERTION 
NODE  NPARTS   DELAY  DURATION     
1     1000     0hour  1day     
13    1000     1day   0hour

The Rate Coefficient Table lists reaction rate coefficients for non-conservative constituents. Different rates can be assigned to different water bodies. The assignment is done using groups -- first you define a group and then you assign rate coefficients to the group.

Field Descriptions

NODE

The node at which the insertion is made.

NPARTS

Number of particles.

DELAY

Delay before the first insertion after the beginning of the PTM runs. The unit of time needs to be attached without spaces.

DURATION

Interval over which insertion is evenly distributed in time. If the time is set as zero, all the particles are inserted instantaneously. The unit of time needs to be attached without spaces.
