I am trying to select all boundaries in a certain plane in Comsol 4.2. It is almost impossible to select by hand beacuse there are 1600 boundaries in the plane. Can someone tell me how to do this? Thanks very much! Baofeng 1 decade ago Hi you can also define several views and remove...
Hello, I am trying to automate my COMSOL model via the LiveLink interface and I am struggling at the geometry part, where I need to transform all my boundaries into "solid". I tried the following: index=mphselectbox(model,'geom1',['-wd' 'wd';'-wd' 'wd'],'boundary...
How to select all boundaries in a particular planeLogin
Say you are working on a modeling case where loads are moving in such a way that they cross over different mesh elements and boundaries during the simulation. In these cases, among other instances, you may want to apply a boundary condition to only part of the geometrical boundary or only ...
It is possible to change the selection of domains, boundaries, or edges for which we display the numbers. For this, we use theGeometric Entity Leveldrop-down menu at the top of the window. TheQuality Measuremenu lets us choose from a list of quality measures, including: ...
how the heat transfers from the right to the left or from the outer boundaries inward to the center of the domain. So we can name thisInward heat flux. And again, we can name the point graphInward heat fluxand plot this. You can see the heat flux, in green, going from 0 to ov...
The experimentally determined lasing threshold (ρ1) and the saturation threshold (ρ2) are shown as dashed lines; they cross the calculated phase boundaries at electronic temperatures of 600 and 900 K, respectively. These electronic temperatures are the upper bounds of the estimated electronic ...
In the view above, only boundaries have been hidden, but we could have also hidden other geometric entities such as domains, edges, and even points! To do so, however, you need to create additional Hide for Geometry nodes, since you can't select more than one type of entity to hide ...
When applying model settings to boundaries, the numbering becomes important. The figure below shows what the boundary condition for the cool side of the heat sink looks like: The boundaries are easily identified in the Graphics window on the right. The corresponding numbers are seen in the Heat...
You have also all the custom settings, you can add several "size nodes, as well as dimensions, and the latter allows you to define geoemtrical functions for the node density distribution too Another term I use are "hard mesh points", this is typically when you add internal boundaries, or...
