Import a matlab file in comsol

In summary, the conversation discussed the issue of importing a text file into Comsol to create a 3D geometry. It was suggested to use a "geometry object" in Comsol, and possibly use Matlab to create the geometry. Another option was to use a CAD program like Solidworks. One person mentioned using Maple13 and exporting a picture as a .dxf file, but there were concerns about converting 3D geometry into 2D.

Hello,
I have a file with points and I want to create a 3D geometry in Comsol, but it's impossible to load a txt file in this software.
In Comsol we can import something called "geometry object" and I know it's possible to create this geometry with Matlab but I don't know how to do.
Can someone help me ?

hi,
I want to do the same thing but can't figure out how...
did you find a solution? if so could you help me please?
thanks

Importing stuff into comsol is all about formatting. Just draw something in COMSOL, then export it. Using the same format of the file you exported just copy and paste your MATLAB data into it.

FYI, if your just importing geometry into comsol, its a LOT easier just to do it with a CAD program like solidworks.

hey guys,

try to use maple13 to creare geometry.. then export picture as .dxf (drawing exchange format)

COMSOL can read .dxf geometry BUT in my case it covert 3d geom into 2d..

if anybody know how to treat it, please let me know.
