how to plot the velocity profile between any two points in Comsol 4.2

In comsol 3.5, when I want to get the velocity profile from (0,0) to (0,4), I could use postprocessing--> cross section plot parameters --> line plot, then I can input cross section line data. However in Comsol 4.2, when I try to plot 1D plot --> line graph, I can only choose the boudaries as the line. Could you tell me how to plot the velocity profile between any two points in Comsol 4.2? Thank you.

Hi,

In the results section under data sets you need to create a 2D/3D Cut Line where you can specify the start and end points, then you can create a 1D plot a choose as a source the Cut Line you created before.

Cheers

Dear Amir,

I am going to plot additional cross sections parallel to the first one I defined. I checked Additional parallel line and entered the range. However when I click on plot icon to see the lines I only could see the first line and subsequently one velocity profile. How could I resolve the problem?
Since I want to take many cross sections I hate to do it manually for each one.

Thanks and regards,

Dear Ivar,

I tried it in your way, but still does not work. Any other recommendation?

Regards,

Hi

you need a "-range(0,0.1,1)" or a range(0,-0.1,-1) I would expect

the direction of "s" is defined by COMSOL so depending on the observation direction you need either + or - values, the coordinate arrow is there now in the plot to help you decide

Good luck
