Arrow plot only in the part of the domain

I have a very narrow geomtery (length>>diameter). Is there anyway to use the arrow plot only in the part of the domain (where the important phenomenon takes place)?.

I tried arrow plot with the the preserve aspect ratio in the view unchecked. Arrows look like horizontal lines.

Hi

you can add a "filer" subnode to your plot and set a Boolean condition there in, or select only 1-2 domains (easier ifyou cut your volume into regions of interest, a few additional internal boundaries are not RAM demanding, and often handy to perform postprocessing on

Thank you, Ivar. I very much appreciate your help.

Using filter subnode plots arrows only in the required region which is good for me. However it still shows the whole geometry even though I am plotting only in 1/4 of the length. Can we specify the axial length scale in the plot settings using boolean operations?.

I am not yet very comfortable with creating good geometries. Is it easy to cut the final geometry into small domains? or do we need to start from the scratch?

Hi

not ure about that, but a cleaner way is to make a new data set direced from the original solution (right click data Set) and then include only some selected domains

There is no major difficulty, or complexity by adding several internal boundaries. These can be (in 2D) single lines cutting the geoemtry (i.e. a box) from one side/edge to another or from one vertex to another. Note that by default a "line in COMSOL is a polyline (joint set of lines, that by default will loop around to frm a domain. In 3D you need to define surfaces, or via workplanes with a closed loop surface
