New physics promises to increase accuracy, improve product safety and reduce failure.
MSC Software just announced the 2014 release of their simulation software Marc. MSC Marc is known for nonlinear and multiphysics simulations. Marc’s simulation technology has various applications including electronics, medical, rubbers and automotive.
Marc’s 2014 release includes improved 3D crack propagation simulations which will accurately predict product failure. Engineers will be able to simulate high cycle fatigue and ensure that cracks will not spread into a critical failure. The failure analysis is tested using Paris’ Law and representative cycles calculated within Marc. With this improved failure analysis Marc can better predict maintenance cycles, product life, safety and warranties.
Simulation convergence has also been improved in Marc 2014 using new nonlinear contact. These segment-to-segment contacts will converge calculations with less iterations and user manipulations. Convergence has also been improved with friction models, manufacturing simulations, assemblies and seal installations.
Using the circuit approach, electromagnetic simulations in Marc 2014 are improved by allowing currents or voltages to be applied to a whole system. This whole system approach can be used when assessing the thermal and structure of low-frequency designs, induction hearing and solenoids.
To help cooperation between teams and consultants, Marc 2014 has also introduced a method to import CAD files from almost any program package. Once imported users can perform geometric operations and/or remove small features as needed. These operations help to facilitate the meshing of the model for accurate simulation results.
Speaking of meshing, the automatic function has been upgraded to better support wires, sheets and volumes. The meshing can also be controlled by the user when meshing assemblies, lower/higher order shells, and tetrahedral meshes.
Finally, the new Marc release has updated the simulation of pressure cavities in 3D, axisymmetric and planar models. These simulations will support nearly incompressible fluids and perfect gas law. This will allow for the simulation of seals, bottle filling and hydromounts without modeling the fluid.
