As of September 1, 2016 Sim Specialists LLC is now a division of the established Autodesk reseller, Hagerman & Company.
These high school students used Autodesk Simulation CFD to simulate the aerodynamics of their design in preparation for the national finals to be held at Michigan International Raceway in May.
As consultants who specialize in simulation, we continue to expand our physical testing capabilities. For example, the image below depicts the results from both testing and CFD on a Raspberry Pi unit, which are very compact Linux machines we use for data acquisition and other tasks.
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.
The classic venturi tube, first designed by Clemens Herschel in 1887, has many useful applications in monitoring or controlling fluid flow.
Can you determine which of the venturi configurations below would produce the least pressure drop from the inlet to the outlet? The only design variable is the angle of the discharge taper.

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.
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.
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.
Simulation services for CFD and FEA is a strategic investment. To make it worthwhile, the return on that investment can vary from saving time and money during product development to increasing competiveness in the marketplace. Here we share a few reasons why our clients chose to collaborate with us on their recent engineering projects:
Whether you actively engage in CAE or not, it is around you and influencing your business. Cost, time to market, compliance, competitive advantage, market share, and product performance are only a fraction of the initiatives improved by the engineering efforts described here.
Three (3) ways engineering simulation will impact your business are presented here, from the lens of our expertise that is specific to flow, thermal, and structural analysis (respectively, Computational Fluid Dynamics or CFD and Finite Element Analysis or FEA).
Autodesk invited Sim Specialists LLC to present 2 CFD training classes this year at Autodesk University held in Las Vegas. The content of these CFD simulation classes is now available for free online.
