Altair Flux 2018 Flux 2018 New Features: - Accelerate your design when dealing with 3D complex CAD geometries A number of new tools were introduced in Flux 12.3, which enabled the import of 3D meshes directly from HyperMesh and SimLab, bringing new capabilities for CAD geometry simplification and meshing. Flux 2018 improves the existing workflow, bringing more flexibility as well as making it applicable to any type of application. The following functionality is available: change the order of the mesh elements, build an infinite box after import, account for movement, deal with any type of coil description or importing a surface mesh. - Solving faster in 3D using new HPC capabilities Improvements introduced in Flux 2018 focus on large 3D models with eddy currents. . New mathematical formulations are now available to help the non-linear convergence in such cases, particularly in the frequency domain. . The linear solver has also been updated with the latest version of MUMPS, and the possibility to use it in a distributed memory mode, allowing Flux to run on clusters with larger numbers of cores. This brings great accelerations for 3D models with large meshes. . It is now also easier to benefit from the computing power of remote clusters thanks to the connection of Flux with PBS Works, Altair's industry-leading workload manager and job scheduler for high-performance computing. - Going further in the coupling with mechanical simulation The coupling with OptiStruct for mechanical design has been updated with the new version. For vibration analysis of electric machines, the post-processing capabilities of Flux have been extended with more options in the data visualization and export. For static stress analysis, it is also now possible to export force densities from a magnetostatic model or from a step of a transient magnetic computation to a structural simulation. Not only magnetic pressures but also volumic Laplace forces can be calculated and exported to OptiStruct to compute mechanical stresses. - Efficient power busbar design using Flux PEEC The PEEC (Partial Element Equivalent Circuit) method is now directly available in Flux. Because this solver does not need any meshing of the air surrounding the parts, it is much more efficient than the finite element method to deal with sets of long or flat conductors. It is the tool of choice for the design of power busbars. Resistances, inductances and parasitic capacitances of conductors can be quickly computed and extracted for circuit simulation. Current, power or force densities distributions are natural outputs that can be used with thermal or structural solvers to analyze respective temperature distributions or mechanical stresses in the bars.
