Number of cores A benchmark of three different models, ranging from 5 to 9 million degrees of freedom (DOF), shows a decrease in overall cost and runtime as the number of cores increases. In this example, the best balance of cost and speed occurs at 64 cores.

The Stream toolset in Abaqus enables users to visualize fluid flow data by placing a rake, or a line segment with a number of points specified along its length, allowing the display of fluid flow in the model. An example application is a conjugate heat transfer analysis of an exhaust manifold.

Since we'd already been using Abaqus in vehicle cockpit design and testing for thermal, impact and normal modal analyses, it made a lot of sense to simply develop a new load case for squeak and rattle inside Abaqus.
