Structural Mechanics and Fluid Structure Interaction

CSM++ introduces a new level of multi-disciplinary analysis and design capability to engineers and scientists in diverse fields of science and technology. CSM++ is a finite element based structural mechanics simulation software suite which has been specifically designed, from the outset, to work seamlessly with CFD++, CAA++ and MIME to carry out Multi-Physics simulations involving fluid flows, acoustics, structural deformations and heat transfer.

• Metacomp’s Computational Structural Mechanics (CSM) and Dynamics software suite
• Finite element based
• Designed specifically to work seamlessly with CFD++ to carry out multi-physics simulations
• Advanced User Interface that intelligently guides user through a logical problem set up

• ICSM++ has tightly coupled structural and flow solvers in modeling fluid-structure interactions (FSI)
• Enables a tightly coupled FSI setup process with an easy and consistent user experience
• Allows control and flexibility in tailoring the fluid and structural solvers and their coupling algorithms according to customer needs

ICSM++ heralds Metacomp's vision for a flow structure interaction capability with an unprecedented level of interaction between all the component disciplines. In addition to importing meshes from MIME, ICSM++ can import just the mesh or the complete finite element model from several commercial finite element codes. The integrated GUI can be used to setup, solve and analyze a problem quickly and efficiently.
