In the dialog box, you can select the option for glTF™ files and specify which filename should be used. When pressing the Image Snapshot button (denoted by a camera icon), a dialog box opens. Results can be exported either by adding an Export Image feature to the model tree or simply clicking the Image Snapshot button at the top of the Graphics window. Note that only 3D results can be exported this way, since the glTF™ and glb file formats support 3D graphics only.

The COMSOL® software exports GLB-files that can be used to easily open and manipulate the geometry in other tools.

How to Export a 3D Results Plot from COMSOL Multiphysics®Īs of COMSOL Multiphysics® version 5.4, you can export results as glTF™ files. It is possible to convert a GLB-file to a glTF™ file and vice versa. The GLB-file format makes it easier to manage the transfer of 3D content, via a single binary file that contains all of the information that is necessary to define a 3D object in a scene.The glTF™ file format is a collection of files that describe the 3D scene as well as the coordinates, colors, and more.There are many organizations and conversion programs that support glTF™, including the graphics industry, software vendors, and open-source players. This means that the graphics file format is good for exporting visually strong 3D results, but not for exporting geometries and results that should be used for further modeling.įor 3D results, you can use the glTF™ file format.

The emphasis for the glTF™ file format is on the display of the 3D figures and not the accuracy of the exported geometry. It can be used to transfer 3D scenes and models between programs. The Khronos Group is known for two of its most famous APIs, OpenGL® and Vulkan®, which are used by graphics cards to provide fast and high-quality 2D and 3D graphics, but they in addition developed a file format called glTF™ (short for GL Transmission Format). The Khronos Group is an organization that helps graphics vendors by creating open standards that can be used by anyone to create platform-independent graphics file formats and APIs. The unstructured VTK® file format (VTU) is the most versatile file format for storing numerical results and can be used by other software programs for further analysis and simulation.
