Geometry Solutions

My 3D model geometry does not become transparent even if I switch on transparency. In COMSOL 4.2 on Windows and Linux, switching on transparency may not make the geometry transparent in the main window. It works...
Version: 4.1,4.2,4.2a - Platform: Windows,Linux

The associative geometry capabilities in COMSOL Multiphysics ensure that model settings are automatically updated for changed geometries, for example during geometry parameterization. When the topology does not change...
Version: 4.2 - Platform: All Platforms

When I open a 3D model from the model library, or create a a 3D object, for example by extrusion of a circle, or try to view a 2D mesh, I get an error message that includes any of the following strings: Error: 9040...
Version: 3.5a - Platform: All Platforms

How do I take advantage of the symmetries in my COMSOL model? Using Symmetries to Reduce Model Size By using symmetries in a model you can reduce its size by one-half or more, making this an efficient tool for...
Version: 4.0,4.0a,4.1,4.2 - Platform: All Platforms

Why do I get the error message “Internal error in geometry decomposition”? [reference id="1089"]Note: if you use COMSOL 4 and have any of the CAD import products, please refer to solution 1089.[/reference] This...
Version: 3.5a,4.0,4.0a,4.1,4.2,4.2a - Platform: All Platforms

This solutions gives some tips and tricks on how to succeed with deformed meshes. ##Basics A deformed mesh can be useful if your model geometry is moving or changing shape with time, or if it deforms in a prescribed...

Can COMSOL Multiphysics handle polar, spherical, and cylindrical coordinates? And how can I define these coordinates? COMSOL 4 To add another coordinate system to the Model Builder, right-click Definitions, select ...
Version: 3.5a,4.0,4.0a,4.1,4.2 - Platform: All Platforms

Can COMSOL Multiphysics import topological data, meshes, and images? Topological Data, GIS, Digital Elevation Models (DEM) If you have topological information saved in the DEM format, you can bring it into your COMSOL...
Version: 4.2a - Platform: All Platforms

Associative geometry is a method that COMSOL Multiphysics uses in the graphical user interface to associate physics, mesh and other settings to the geometrical objects. Associative geometry means that simple geometric...
