Hello,

I am using Particle tracing module and a Parametric sweep to compute the final position of a set of nanoparticles depending on their initial position. After that, I would like to sum all the partial solutions, but doing it one by one through "Data Sets->Join" is kind of tiresome.

Can you give me some advise of how could I do it?

Thank you very much!

Juan,

check this blog contribution: https://www.comsol.de/blogs/using-the-previous-solution-operator-in-transient-modeling/

A similar approach also works for parametric sweeps and for summing or do other things along a sweep.

Cheers Edgar

Hello Edgar,

Thank you very much for your answer. Unfortunately, I was not able to implement the method that is described in that post. For the moment I am using the following algorithm:

sum(withsol('sol1',variable,setind(parameter,i),setval(t,t_0)),i,1,xx)

It is slow, but it works. I will try to give a second chance to the other method.

I think that you should consider using the Combine Solutions study step.
