Impact is a finite element software that operates with an explicit time stepping algorithm.
One of the most notable features that make Impact a top choice is its virtual 3D model, created with a pre-processor or built-in Fembic language, on which simulations can be run. Results obtained from the simulations can then be viewed in a post-processor for further analysis. While Impact is designed to interface with the included pre- and postprocessor by default, there are advanced pre- and postprocessors available, including Gmsh and GiD, that can provide seamless integration.
Moreover, Impact has rudimentary support for the Nastran file format for more flexibility. The program is constantly evolving, thanks to its team of volunteer developers from around the world. Their mission is to create a compact, understandable program that is easy to use, ensuring continual improvements are made.
Impact is licensed under the GNU Public License, which enables anyone to use and modify the program provided they adhere to the licensing agreement. Since it is written in Java, Impact works seamlessly on most hardware and operating systems, making it a convenient choice for users who need flexibility.
With the new release of Impact, users can experience even more flexibility and improved features. Key enhancements include the ability to save the entire preprocessor model in the .in file and script drive the geometry and FE model manually by editing the .in file and importing it into the preprocessor. A bug in the post-processor has been fixed to ensure Gradient Result is now visible in the OpenGL-accelerated version, enhancing the user experience.
Overall, Impact Project is an excellent software product that can handle a wide range of simulation requirements for dynamic events without burning a hole in the user's pocket. Its open-source status, improved usability, and constant development make it a top contender in the market.
