Someone (Daniel Smith perhaps) please let me know if there is flawed logic here. The rst and perhaps most important of them was 'Cap Faces'. Z = IF(particleindex<500,-1,1) for the charge of the same respective ions 3.4 Tools in COMSOL Multiphysics There were a couple of tools in COMSOL that turned out to be extremely im-portant and well- tted for tracing particles in a gas ow. M = IF(particleindex<500,35.453/N_A_const,22.98976/N_A_const) where N_A_const is a physical constant in COMSOL for avogadro's number

Multipurpose: New multiphysics interfaces for particle-field interactions and fluid-particle interactions, inelastic collisions, and release sampling from velocity distributions for particle tracing simulation.What's new in Comsol 5.1 Update1:- Table windows in the COMSOL Desktop will now never appear blocked. Depending on other licensed products, the Model Wizard may include options other than those that are shown here. Question on this, what if I wanted to associate particle masses with charges found in the previous random number generator? Is it possible to just assign certain particle indexes to specific properties? Say, with 1000 particles, The COMSOL discussion forum covers a wide variety of simulation topics. licenses for COMSOL Multiphysics and the Particle Tracing Module. For visualizations throughout volumes, a new Grid data set is available.
For example, electromagnetic or acoustics wave far-fields can be evaluated and visualized outside the mesh on a user-defined parameterized surface or curve.
For my case, I think I would need to do that for my sodium and chlorine ion masses but also for the charge of each particle being With version 5.1, you can now evaluate and visualize spatially varying expressions and fields outside the mesh. Perhaps this would give you half of your particles at 1 µg and half at 1.2 µg. Similar to what Daniel Smith said, I would think if you were to use an "IF" statement you could get essentially the same effect.ġE-6+IF(random(particleindex)<0.5,0,2E-7)
I am looking at doing a simulation with salt water (sodium and chlorine ions).
