Besides being widely applied in open-source and commercial projects, Open CASCADE Technology (OCCT) is actively used at an academic and research levels around the globe. To provide insight into it Open Cascade launches a new section devoted to OCCT-based research on a renovated Development Portal. It gathers hundreds of research and scientific articles from prominent universities and organizations in more than 40 countries.

Having received numerous requests from the open-source community Open Cascade decided to publish free trainings to ease access to Open CASCADE Technology (OCCT). Free presentations available on the recently renewed Development Portal cover Preliminaries, Geometry, and Topology topics.

Preliminaries subject aims at general OCCT-related problems. It focuses on general tasks like getting OCCT, its structure, building from sources, etc. In addition to Open CASCADE Technology overview, the training provides several performance tips and describes Draw Application functionality.

Gmsh

Gmsh is a 3D finite element mesh generator with built-in pre- and post-processing facilities.

Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface, in ASCII text files using Gmsh's own scripting language, or using the C++, C, Python or Julia Application Programming Interface (API).

FreeCAD

FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size.

Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects, adjust dimensions or extract design details from 3D models to create high quality production ready drawings.

CAD Assistant

CAD Assistant is a freeware viewer and converter for 3D CAD and mesh files, developed by Open Cascade.

CAD Assistant is based on open source libraries (Open CASCADE Technology, Qt, FreeType, FreeImage, etc.) and employs open formats for CAD and mesh data (STEP, IFC, IGES, BREP, glTF, JT, PLY, STL, OBJ, 3DM). It also supports a set of other file formats like DXF, SAT (ACIS), XT (Parasolid).

It is made to promote open technologies and brings the power of these technologies to the hands of engineers working with 3D data.

SALOME

SALOME is an open-source software that provides a generic Pre- and Post-Processing platform for numerical simulation.

It can be used as a standalone application for generation of the CAD model, its preparation for the numerical calculations and post-processing of the calculation results or as a platform for integration of the external third-party numerical codes to produce a new application for the full life-cycle management of CAD models.
