With STAR-CCM+’s unique finite-element volume (FV) stress solver, perform Flow-Thermal-Stress co-simulation within a single environment.
STAR-CCM+ is a single, integrated, multi-disciplinary environment for solving engineering problems involving flow of fluids or solids, heat transfer and stress. STAR-CCM+ has a unique finite-element volume (FV) stress capability that lends itself well to co-simulation FSI as well as Flow-Thermal-Stress co-simulation with low CPU and memory d

  • Conjugate Heat Transfer (CHT) refers to the simultaneous heat transfer in both a solid and a fluid where the conduction in the solid material and the convection in the fluid are analyzed simultaneously . Shown is the flow thermal stress analysis of the NASA C3X turbine blade

Solid Stress functionality uses material models that include linear isotropic elastic materials and Rayleigh damping and supports boundary types that range from simple displacement to force to traction.  For improved accuracy, contact impact interfaces can be modeled as welded or without friction.

With Solid Stress capabilities, implicit or explicit FSI, small displacement FSI and large displacement FSI can be run with ease as there are no 3rd party codes involved and no file mapping required.

Mechanical co-simulation conditions become available in a solid simulation when you select the Solid Stress model.  One-way coupling is activated through an export option and two-way coupling is activated through an export & an import option.
