Hello,

I'm trying to get the area of a boundary, unfortunately without success.

Reading the help for measurement tool in the API document (P.151), I can conclude to the following code lines:

ie: to measure a face on a single block
__________________________________________________________________

model.geom('geom1').measure.selection.init(2);
model.geom('geom1').measure.selection.set('blk1', [4]); % Measure face #4
model.geom('geom1').measure.getArea(4);
__________________________________________________________________
This code sequence generate error : No appropriate method, property, or field getArea

The only line on which help document is passing quickly over is the last one: I don't know how to correctly write this line. getBoundaryArea, getArea ?



Regards,

Finally, to get the area :

model.geom('geom1').measureFinal.selection.geom('geom1', 2);
model.geom('geom1').measureFinal.selection.set([4]);
model.geom('geom1').measureFinal.getVolume
Finally, to get the area : model.geom('geom1').measureFinal.selection.geom('geom1', 2); model.geom('geom1').measureFinal.selection.set([4]); model.geom('geom1').measureFinal.getVolume

Hello Gabriel,

I know its been so long since your post but I am posting here since I couldn't find any relavant post about this.

I want to measure the length of an edge, area of a boundary etc. using the measurement tool in COMSOL. I found out that using the following syntax:

model.geom(<geomtag>).measure.selection.named(<edgeselectiontag>)

in Matlab Livelink does not actually return the edge length. It just returns the following but not the actual length of the edge.

Dimension 1: Geometry Geometry; Domain 31

Is there a way to get the value of actual dimension into the matlab workspace?

Thanks!
