Thanks for replying.

In comsol 3.2(FEMLAB), the boundary plot was line.

But as I know, in 4.0 I can't boudary plot in line..

Is there no line boundary plot in 4.0a ?

THanks

Hi

it depends ;)

in what dimensions are you using ? a Boundary is a surface in 3D, or a line in 2D.

So if you are in 2D and V4, you may add a line plot : right click Results add 1D plot group. Then right click this new node and add a line graph, select your boundary and set your variable (CNTRL + SPACE gives yuo the default list)

if you are in 3D a boundary requires a "2D plot group to which you add "surface" plot node.

If you want to do a line cut plot on a 2D surface boundary (another case) then you can do this by creating a new Data set (right click "Data Sets" and add a split line + coordinates, or select an edge if it exist for your case

One thing forget 4.0a, get a newer 4.1 patched version, see with your local COMSOl rep, or sysadmin

Good luck

Thanks IVAR.

I am sorry but there was my mistake.

I mean the boundary "height" plot.

Can I plot the 1-D height boundary plot?

Thanks

Hi

That is a good question !

Indeed, that one I do not see in V4, for 1D,
it's there for 2D, as a sub node of the surface plot.

Perhaps something to ask support about, and call it a suggestion for next release ;)
