17 Jul K&C Releases FEMFRE Version 1.0
K&C releases Version 1.0 of FEMFRE, K&C’s meshfree computational solid dynamics (CSD) solver. K&C is currently providing FEMFRE to US DoD Agencies for evaluation and is pursuing broader distribution and support of FEMFRE to the modeling and simulation community. A version of the FEMFRE User’s Manual is now available for public distribution.
FEMFRE is an explicit dynamic code that solves high-rate CSD problems involving materials and structures in extreme environments. The code employs a Galerkin meshfree solver that uses the reproducing kernel particle method (RKPM) as the overarching framework. CSD problems involving materials and structures undergoing extreme material deformation, breakup, and evolving contact can now be solved more effectively using FEMFRE’s new powerful simulation capabilities.
KEY FEATURES
Some key features of FEMFRE include:
- Unconditional numerical spatial stability. FEMFRE’s advanced semi-Lagrangian solver will not terminate due to issues that plague finite element and SPH solvers, like negative volumes for inverted elements, spurious spatial and tensile instabilities, and others.
- Free from ad hoc numerical parameters. There is no need to develop and tune numerical controls like element erosion, hourglass, bulk viscosity, contact, and others.
- CFD coupling and multi-physics capabilities. FEMFRE can provide coupled thermo-mechanical solutions, and it can also be coupled with CFD solvers to solve complex fluid-structure interaction problems, which K&C intends to make available to FEMFRE users in the future.
