Hello Hamid,
Several ways of achieving what you want are presented on the COMSOL Blog:
www.comsol.com/blogs/maximum-evaluations-on-parallel-sections/

Yet another way is to create a method in an app. That assumes that you have version 5.0 or later on Windows. Big picture: repetitive post-processing (or pre-processing, for that matter) tasks are often extremely easy to automate using a method in an app.

Thanks Jeff
That was great. I think I understand everything there except 'quickz'.In my case, since it is a 2D model I will replace cpl1 with cln1. The u should be converted to mf.normB in linear mode (1). But what is quickz?

Regards
Hamid

P.S.: I paste the program for quick reference.

z = [z1 z2 z3 zn];

for i = 1:length(z)

model.result.dataset('cpl1').set('quickz', z(i));

umax(i) = mphmax(model,'u',2,'dataset','cpl1');

end

plot(z, umax)

Hello Hamid,
You're basically asking COMSOL to define the cut plane data set using a plane specified quickly by its being normal to the z direction at the z-coordinate z(i), as opposed to the more general ways of defining a cut plane (with 3 points or, alternatively a point and a normal). If the above is not so clear, please take a look at the GUI interface for creating a cut plane and you'll see what I mean.

Hi Jeff
Actually, I'm working in 2D. It does not make sence for a line. Also I do not want ot create any thing, I just want to switch from one line to another.

Indeed, in your 2D case, things will be slightly different from the 3D example in the blog, although the general approach is the same. You do need to create data sets though.
