What is Cast2cloud ?

Cast2cloud is a web front-end for the finite element solver Cast3M. We provide everything you need to start using Cast3M. With an intuitive design, we will help you to build a Cast3M-readable mesh, translate your complex problem into Cast3M's language and then visualize the computed results. All these awesome features are available directly from your web browser. To discover more about Cast2cloud, please visit our Youtube channel

Why Cast3M ?

Developed by CEA ( French Alternative Energies and Atomic Energy Commission ), Cast3M is a open source, powerful, flexible tool that can be used to design, dimension and analyze structures and components for nuclear energy industry as well as for other traditional industrial areas. Cast3M allows modeling numerous mechanical and thermal phenomena of materials. For more information and download, please follow this link
