![]() What we need to do depends on the type of simulation as well as the contents of the files. When importing these files into COMSOL Multiphysics, the most important concern is how to prepare them for simulation. Both formats contain a mesh, although the NASTRAN® format can contain both volume and boundary mesh in addition to all of the other information mentioned above. If we compare these two formats from the point of view of a COMSOL Multiphysics user, we will find some similarities. The COMSOL Multiphysics software supports the import of the mesh, selections, and materials. This format supports hundreds of NASTRAN® file entries describing various mesh elements, loads, and materials - making it possible to define a complete finite element model. The NASTRAN® file format is the most common format for exchanging 3D meshes among simulation tools. Image credit: Mark Yeoman, Continuum Blue Ltd., U.K. This sequence shows a number of the steps that can be taken to simplify the mesh and thus the simulation of this geometry: the imported surface mesh the generated geometry the geometry after partitioning and, finally, embedding this geometry into a surrounding volume and the final mesh that results from this. Importing this type of file results in multiple geometric objects, the number of which depends on how many such sections are found.Īn STL file of a vertebra imported into COMSOL Multiphysics. Many programs support text STL files, which can contain several of these sections in one file. In its standard form, a text STL file begins with a line starting with solid and ends with a line starting with endsolid. COMSOL Multiphysics supports multiple objects in a single STL file, according to a widely used nonstandard extension of the format. STL files contain only the triangulated surface, which we can also call a surface mesh, of a 3D object. The STL format, as mentioned previously on the blog, is one of the standard file formats for 3D printing, but it is also often used as the format for 3D scans. Learn how to utilize this functionality as well as how to achieve good results when importing STL and NASTRAN® files. The COMSOL Multiphysics® software contains features for dealing with these files. However, performing simulations on these realistic objects can be challenging, particularly when preparing the geometry. STL files originating from 3D scan sources and meshes in the NASTRAN® file format are often used as bases for geometries.
