I am trying to make a comsol solid object in comsol with matlab using the scripts. I have faced a problem while trying to make triangular solid faces. To my surprise, it works for some of the faces and not for the others. I have included coordinates of a face which works and one which does not. See blow:

Case 1:coordinates of a face that I could be able to make a solid face:

X1=[98.8039, 98.1607,108.5693]'
Y1=[36.7363, 27.3986, 27.1507]'
Z1=[158.4480,122.2644,133.5170]'
With these coordinate points I am able to draw a patch of the face in matlab and able to make the face usig face3 (X1, Y1 ,Z1) and able draw the face using geomplot.

Case 2: coordinates of a face that I could not be able to make a solid face:
X2=[ 90.2213,109.3981,98.9929]'
Y2=[ 74.0388, 29.0457, 45.9889]'
Z1=[ 99.6007,101.8802,104.3517]'
With these coordinate points I am able to draw a patch of the face in matlab and not able to make the face usig face3 (X2, Y2 ,Z2) and not able draw the face using geomplot.
The command g=face3(X2,Y2,Z2) does not give any error but geomplot(g) gave the following error.

Java exception occurred:

looking forward to your reply!
with many thanx in advance!
