Meshing in a Single, Integrated Simulation Environment

Meshing in a single, integrated simulation environment (e.g., Caedium) for Computational Fluid Dynamics (CFD) is different, in a good way, from meshing in a dedicated mesh or post-processing tool. An integrated CFD simulation environment has the standard meshing tools, but in addition upstream you have a full geometry engine to create and modify geometry as needed, and downstream you can use the same meshing tools for visualization, such as seeds for streamlines and surfaces for results interpolation. You are not forced into a linear progression through the CFD simulation process, because often it requires multiple visits backwards and forwards (non-linear) through the tool chain to get to a final result. Also the visualization of mesh metrics (e.g., surface mesh quality) is identical to general flow field visualization (e.g., pressure), which minimizes the number of concepts you need to learn.

CFD Geometry Creation

Given the option, it is often better to create geometry specifically for your Computational Fluid Dynamics (CFD) simulations. It is even better if your CFD system supports geometry creation. Then you can stay within a single integrated simulation environment for your entire task without the need to learn or purchase additional software packages.

November 2015: FYI DIY CFD

This month is the month for you to give Computational Fluid Dynamics (CFD) a go. There has never been a better time to benefit from CFD, so find out why the time is now for your own DIY CFD projects. Then, for a taste of something technical, see why CFDers prefer analytic geometry over faceted geometry.

If fluid flow is a primary driver for your design project then Computational Fluid Dynamics (CFD) is likely to be a cost effective way to help meet your goals. You could outsource your CFD to consultants, but in the long run it usually pays to do it yourself.

September 2015: Spinning Paper Wings Meet CFD

The theme for this month's newsletter is spinning paper wings. Let Computational Fluid Dynamics (CFD) be your guide as we progress from a simple spinning paper sheet to a tumblewing, and finish up with a control method (walkalong) for a tumblewing.

Tumblewing Meets CFD

Although a sheet of paper can be made to fly by spinning, it isn't always reliable. By adding winglets and flaps with 4 simple folds we can improve the stability of the wing and in so doing produce a tumblewing. How do the aerodynamics of a tumblewing compare with a sheet of paper? It just so happens Computational Fluid Dynamics (CFD) can help, just as it did with the simulation of the spinning sheet of paper.
