COMSOL 6.2 - mphviewselection

Display a geometric entity selection in a MATLAB® figure.

mphviewselection(model,geomtag,number,entity,…)

mphviewselection(model,geomtag,number,entity,…) displays the geometric entity number of type entity in MATLAB figure including the representation of the geometry geomtag.

mphviewselection(model,seltag,…) displays the geometric entity selection seltag in a MATLAB figure including the representation of the geometry.

The function mphviewselection accepts the following property/value pairs:

Example

Plot boundary 6 using yellow color:

model = mphopen('model_tutorial_llmatlab');

mphviewselection(model,'geom1',6,'boundary',…

'facecolorselected',[1 1 0],'facealpha',0.5)

Plot edges 1 to 8 using green color:

mphviewselection(model,'geom1',1:8,'edge',…

'edgecolorselected',[0 1 0])

Add an explicit selection for boundaries 7 to 12 and plot the selection in a figure:

model.selection.create('sel1','Explicit').geom(2).set(7:12);

mphviewselection(model,'sel1');

Add a selection to get the vertex indices with the box delimited with the coordinates [-1e-3 11e-3;-1e-3 11e-3;9e-3 11e-3] and plot both the selected entities and the selector:

box = model.selection.create('box1', 'Box');

box.set('entitydim', '0');

box.set('xmin', '-1e-3').set('xmax', '11e-3');

box.set('ymin', '-1e-3').set('ymax', '11e-3');

box.set('zmin', '10e-3').set('zmax', '11e-3');

mphviewselection(model,'box1','facemode','off');
