A list of problems that i have during using MercuryDPM

1.I could not use a VTK-Writer Command at Beginning,which serve for Visualization of Particles && Walls.

Solved:Please use Trunk Version not released Version

PS:Note If you want to reinstall your Trunk Version please first delete the older version totally!

 

2.Data corrupted short time after particle-wall collision

Solved:Maybe change the time step size

normally:collision time/50 (tc/50)

 

3.Overlapping of particles,fail to define species between particles

Once i defined specie for particles and walls individually and a mixed species(I remenber that i saw this code type in a tutorial of multi-specie problem.I have the term “specie” misunderstood.

 

Solved:Just define one specie for both wall-particle

 

PS:In species, Density,Stiffness,Dissipation etc. are defined, Stiffness and Dissipation describe an interaction(collision property).We dont need specify property of walls,because we just focus on particles.)

 

Hope you have fun in simulation
