How to simulate a point-wise concentrate load traveling along a structure?
Now I'm working on the moving-load problems of the beams and plates. I want to use comsol to simulate a point-wise force or mass traveling along a beam, or traveling along a path on the plate surface, and explore the deformation... Read more »

evaluate statistical quantities over all particle
running a charged particle tracing simulation with 100(say) input electrons gives a final quantitity qx(x-coordinates) of al particles. How do I evalute say the mean of qx( over all the elctrons) at any time step? Read more »
