[start here] Hello, I am using COMSOL version 5.5 on Windows 10.
I have an external MATLAB function to calculate the velocity of a particle after it hits a Wall. I have followed the instructions given in the "Introduction to Livelink for MATLAB" and the section on using external functions for MATLAB. I can create a MATLAB function which returns the new velocity of the particle. I can select as Wall condition "General reflection" and there I can provide the name of the MATLAB function (or functions) for the reflected particle velocity. So far so good. However, the particle that hit the wall from the vacuum (as calculated by COMSOL) and then enters the material (as calculated by MATLAB) does not return to the same point and so I need to pass not only the velocity, but also the position of the particle back to COMSOL. Is there a way I can do this ?
Thank you in advance Chris Walker
