Mexico Trip Inspires CFD on 'El Castillo'

Mexico Trip Inspires CFD on 'El Castillo'

Sim Specialists recently traveled to Mexico City to deliver onsite FEA and CFD simulation services.  The trip reminded me of a documentary I watched a few months ago about El Castillo, a Mayan structure located in the Yucatan peninsula region of Mexico.

One of the numerous fascinating characteristics of this monument is that during the spring and fall equinox, the shadows cast across the northwest corner and onto the north stairway give the illusion of a descending serpent.

I thought this would be a cool application to validate the Solar Heating capability of Autodesk Simulation CFD.  

Smoke Modeling with CFD

Smoke Modeling with CFD

CFD simulations of flow and thermal fields surrounding a smoke source, provide a visualization of smoke egress that can be leveraged to guide the design of smoke control systems required to meet smoke and safety regulations.

This article reviews building design considerations for smoke control systems that are enhanced by CFD smoke modeling.

Free Thermal Summary Utility Speeds Up Post-Processing

Free Thermal Summary Utility Speeds Up Post-Processing

As users of Autodesk Simulation CFD and Autodesk Simulation Mechanical on a daily basis, we run into certain tasks that are repetitive or time-consuming.  For many of these situations, it can be beneficial to develop a script to increase proficiency.

One example is processing the temperatures for a large number of components,  which is typical for complex electronics assemblies.

Units in CFD and FEA plus Free Flow Calculator Utility

Units in CFD and FEA plus Free Flow Calculator Utility

During a recent Google search, I stumbled across this interesting NASA paper which determined the root cause for the loss of the Mars Climate Orbiter in 1999 was a mismatch of units. A subroutine coded for thruster data in metric units was instead fed English units, which resulted in a trajectory error.

Even with advancements in modern CFD and FEA software interfaces, the burden is still on the user to get the units right.  

While there are many good online calculators and unit conversion sites, we thought we would share the free VolFlowCalc utility that we developed and use internally.
