Structural simulations now provide shock response spectrum analyses and offer material activation for additive manufacturing. Fluid flows also see functionality that enable fluid-structure interaction (FSI) for multiphase flow and multibody dynamics.Įlectromagnetics enhancements include structural-thermal-optical-performance (STOP) analysis for ray optics. The Computational Fluid Dynamics (CFD) module sees added functionality for large eddy simulations (LES) and, according to the company, significantly updated modeling tools for multiphase flow. The AC/DC module features a new part library with fully parametric and ready-to-use coils and magnetic cores. In this topology optimization of a hook, the simulation finds the optimal material distribution when the structural part is subjected to two load cases. Among the various performance improvements is an updated memory allocation scheme that, the company says, gives several times faster computations in the Windows 7 and 10 operating systems for workstations with more than eight processor cores.Ī new topology optimization tool makes its first appearance in COMSOL Multiphysics 5.4. Users can now also organize Model Builder nodes into groups and assign custom coloring schemes to geometry models. The company adds that by combining the Composite Materials module with new functionality for layered shells available in the COMSOL Heat Transfer and AC/DC modules, users can perform multiphysics analysis such as Joule heating with thermal expansion.ĬOMSOL Multiphysics version 5.4 also introduces numerous productivity improvements such as the ability to use multiple parameter sets in a model, including parametric sweeping over multiple parameter sets. The new Composite Materials module provides a dedicated set of modeling tools for working with layered materials. “This is a level of freedom that the industry has not seen before.” letting specialists compile an application into a single executable file for unlimited use and distribution,” said Svante Littmarck, President and CEO, COMSOL, in a press statement. In this wind turbine blade example, the top image shows a visualization of the shell local coordinate system (top), the von Mises stress in the skin (middle) and the spars (bottom). COMSOL Multiphysics 5.4 debuts a new Composite Materials module with dedicated modeling tools for working with layered materials.
