Material Point Reservoir

Introduction

Simulations in NairnMPM are currently limited to a fixed number of particles. To all for simulations options to delete particles or inject particles, the code implements a reservoir of material points. This reservoir is current only implement in OSParticulas but will be moved to NairnMPM soon and will be then be documented further.

Deleting Particles

An feature that deletes particles, moves those particle into the reservoir. The current options to delete particles are

• LeaveLimit Command - is this commands (maxNum) parameter is negative, particle that leave the grid are deleted from the simulation and moved into the reservoir
