The main benefit of the Harmonic Balance method is that you can solve unsteady flow problems using steady flow solver techniques, as in this analysis of a NASA rotor compressor blade. This means that the method is often faster and therefore much more cost-efficient than conventional time-accurate time-marching approaches.
Geometry Preparation for Electronics Thermal Simulations Series 2 Part 2
Historically, thermal simulations of electronic systems have utilized dramatically simplified geometric versions of the systems. The simplifications show up in two main ways: Part count reductions, where assemblies that might actually contain thousands of components are simulated using 200 parts or less. Individual components are dramatically simplified so that they end up as nearly or completely orthogonal even when in reality they involve highly sculpted, organic shapes. For some assemblies the inaccuracy, due to these simplifications, is still within acceptable levels, but for many modern...
"Prediction is very difficult, especially if it's about the future" - Niels Bohr, Nobel laureate in Physics Whether you like it or not, as a simulation engineer you are in the prediction game. Put simply, your job is to predict how an abstract design would perform in the real world, hopefully accounting for the most challenging operating conditions that it would likely experience during its working life. Compared with other professional forecasters such as economists, television meteorologists or political commentators, the audience for engineering predictions is more critical and less likely...
Simulation for Subsea Engineering and Flow Assurance
Subsea engineering raises many challenges, especially those issues relating to system integrity and flow assurance. The role of engineering simulation is becoming more important during both field development and operation. This has created increased requirements for detailed analysis, combining complex systems and physics such as multiphase flow, solids management and flow-induced motions. Ongoing development in software technology and reduced hardware costs means 3D simulation of a wide range of subsea and flow assurance applications is increasingly feasible and adding significant value...
