About With CalculiX finite element models can be built, calculated, and post-processed. The pre-and post-processor is an interactive 3D tool using the OpenGL API. The solver is able to do linear and non-linear calculations. Static, dynamic, and thermal solutions are available. Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. In turn the pre-processor can write mesh-related data for nastran, abaqus, ansys, code-aster, and for the free-cfd codes dolfyn, duns, ISAAC and OpenFOAM. A simple step reader is included. In addition, external CAD interfaces are available. The program is designed to run on Unix platforms like Linux and Irix computers but also on MS Windows.	About Prism is Navier AI’s desktop AI engineering platform for hardware, mechanical, aerospace, and other engineering teams. It combines parametric CAD, 3D viewing, physics simulation, code editing, and reporting in one application. Users can describe a part or study in natural language, create or refine CAD, and use AI agents to configure and run physics solvers, write scripts, inspect results, and generate plots, dashboards, reports, or slides. The solver catalog includes 12 solver families, such as OpenFOAM, SU2, CalculiX, Elmer, Project Chrono, and OpenModelica, plus Navier AI’s Ferro solver. Engineers can import STEP files, review scripts, meshes, and solver inputs, and run multiple agents in parallel to explore designs. Prism installs on Windows, macOS, and Linux; local solver workflows run on the user’s computer. The agent requires an internet connection and sends the content it reads to Navier AI’s model backend. Optional cloud compute can run approved solver jobs.
