K&C’s innovative Meshfree Computation Solid Dynamics (CSD) solver.
FEMFRE is developed towards a vision for a truly predictive, large-deformation, solid mechanics solver for simulating materials and structures in extreme environments. Originally designed as a hybrid Finite Element and Meshfree solver, K&C has since focused FEMFRE development towards an advanced, Meshfree, thermo-mechanical solid dynamics solver.
By implementing and maturing Meshfree methods [1-3], including particle and cell-based nodal integration methods, we intend for FEMFRE to solve problems that most finite element mesh-based solvers remain challenged by. These include problems involving:
FEMFRE can now be used as a tool and research platform for those in the modeling and simulation community interested in supporting the vision for this powerful solver. FEMFRE is powered by K&C’s Extreme Materials Library (ExML), which includes a host of common solid materials characterized in our Dynamic Material Characterization laboratory. FEMFRE is therefore applicable to many blast, shock, impact, and intense fluid-structure interaction problems .
K&C’s current efforts for FEMFRE development are in refining, extending, and validating to solver towards the vision for the prediction capability.
