How to Build Geometries from Elevation Data to Model Irregular Shapes
Say you want to build an irregular geometry of a mountain. You can do so by creating a surface of an irregular shape based on elevation data stored formats such as text, image, or DEM files.
Modeling Irregular Shapes: How to Import Curve Data and Loft a Solid
Say you want to model an irregular shape, like a human head. How do you set up the geometry? Here, we go over how to do just that by importing curve data and lofting a solid.
Creating a Model Geometry in COMSOL Multiphysics®

How to Create a Randomized Geometry Using Model Methods
What does cheese have to do with setting up a COMSOL Multiphysics® model? Here, we use the random holes in a piece of Swiss cheese to demonstrate creating randomized geometries with methods.
How to Generate Random Surfaces in COMSOL Multiphysics®
Get a comprehensive background and step-by-step guide to generating random surfaces in COMSOL Multiphysics®, such as rough surfaces and microstructures.
Efficiently Assign Materials in Your COMSOL Multiphysics® Model
To optimize your modeling processes, there are a number of built-in materials available for you to use in the COMSOL Multiphysics® software. Along with these materials are features and functionality that allow you to efficiently assign materials to geometric entities in your model. These tools help expedite the process of assigning materials, specifying material properties, and even comparing the impact of different materials on your simulation results. Here, we’ll highlight three tutorial videos that showcase how to use such tools.
Improved Functionality and Tips for Importing STL and NASTRAN® Files
STL files originating from 3D scan sources and meshes in the NASTRAN® file format are often used as bases for geometries. However, performing simulations on these realistic objects can be challenging, particularly when preparing the geometry. The COMSOL Multiphysics® software contains features for dealing with these files. Learn how to utilize this functionality as well as how to achieve good results when importing STL and NASTRAN® files.
How to Reuse a Deformed Shape as a Geometry Input
Suppose you take a piece of metal — a thin sheet, for example — and apply some mechanical loads. The metal will deform and take on a new shape that differs from the original undeformed configuration. Say you now want to use this deformed object as part of a new geometry construction. You can then solve another physics problem on the new composite domain. Today, we’ll demonstrate how to use a deformed object as an input to a geometry sequence.
