My colleague, Jon Quigley, Director, Multi-Disciplinary Simulation at Altair, submitted the following blog post.

The area of multiphysics has reached an inflection point in the CAE market.  Customers are increasingly requesting solutions that span traditional single physics, and vendors are responding by providing multiphysics -capabilities.  These typically come in two forms:  sequential and co-simulation.  Sequential involves a solver for a single physics producing results that can be manipulated in preparation for a second solver run of a different physics.  An example could be using an FEA code to prepare a modal representation of a structure for further use by a CFD or MBD solver.  Co-simulation applies when two or more solvers are performing a time-forward simulation and exchanging data along the way.  One example is fluid-structure interaction (FSI), in which an FEA code solves the structural portion and a CFD code solves the fluid portion while they exchange data to properly capture the effects that each domain has on the other.    Read More

My colleague Dr. Farzin Shakib wraps up his computational fluid dynamics-focused video blog series, with Part 3 touching upon AcuSolve and its speed and robustness for solving complex CFD problems.

As a follow up to last week’s video blog, my colleague Dr. Farzin Shakib continues the discussion around computational fluid dynamics, today addressing the conservation of mass, energy and momentum in finite element-based CFD solvers.
