Modeling Irregular Shapes: How to Import Curve Data and Loft a Solid

Hanna Gothäll September 20, 2017

Irregular shapes can come in several different formats. For example, we have previously discussed importing STL files and NASTRAN® meshes into the COMSOL Multiphysics® software. These formats are common when working with scanned biological data. In this blog series, we will look at different ways of handling irregular shapes in COMSOL Multiphysics.

Creating a suitable mesh for your FEA simulations is crucial for getting accurate results. In this blog post, we discuss how to check entities reported in mesh warnings and errors, how to view the statistics of a mesh or parts of a mesh, as well as how to plot the mesh and mesh-specific quantities and delimit these plots to selected regions.

Topology optimization can be a useful step in your design process, but the generated designs often require further analysis. With the COMSOL Multiphysics® software, you can create geometries out of your topology optimization result plots and easily export them to CAD software. In this blog post, we discuss how to do so, using both 2D and 3D examples.

When addressing your geometry- and mesh-related support questions, we’ve noticed an increased use of STL files originating from 3D scan sources and meshes in NASTRAN® file format as bases for geometries. Performing simulations on these realistic objects can be challenging, particularly when preparing the geometry. Dealing with these files is now easier thanks to updates in the COMSOL Multiphysics® software. Learn how to utilize this functionality as well as how to achieve good results when importing STL and NASTRAN® files.
