3D CAD


3D CAD modeling is not a sketch pad for ideas, it is a highly accurate virtual environment to test fit, alignment, weight, strength, etc. Each part is drawn as it is fabricated.

Finite Element Analysis

Finite element analysis (FEA) or finite element modeling (FEM), provides an initial verification of design performance. If done correctly, the time required for prototyping is reduced significantly. Otherwise it's just pretty pictures.


Proper constraints. Simulation must reflect reality.


For example, a flange is not bonded through the entire circumference, only at the bolt pattern.

Quality Mesh For accuracy and convergence


This is more art than science - keeping quality high with element count (thus solving time) down.

Mesh independence per ASME V&V 10 and 20


The effect of mesh resolution MUST be taken out of the results. Otherwise all you have is a pretty picture which may have NOTHING to do with reality.

Results Interpretation: Stress concentrations and artifacts.


Certifying the results using quantitative data.

Computer Aided Design

Computer Aided Design (CAD) has transformed the design cycle with 3D modeling.


Real parts: as manufactured


Parts are built in CAD as they are built in the fab shop. This "bottom-up" approach ensures the final product can be built with existing manufacturing capabilities. The trailer frame shown here is plasma cut, then bent on our brake press.

Test each part: fit and assembly


If the part cannot be brought in and attached (weld, bolt, etc) in CAD then it cannot be in real life. On the shown chassis, room is left for welding, deformation due to welding, and heat affected zone.

Simulate: motion, performance, weight


Looping here on the design cycle saves many prototypes. Does it move as desired? Does it hold stress as needed (FEA)? Is it the desired weight? The chassis shown is tested for safety factor of 8.

Finished item: Ready to build


Since the "heavy lifting" was done in CAD, the assembly of these parts will be like lego. No shop-floor modifications. No "on the fly" measurements. Simply precision. Shown, the full assembly of the ExoVac130.

Titanium refinement


We are developing a new titanium refinement strategy to significantly lower costs.

Dense Plasma Focus subcritical assembly


Along with Dr. Staack at Texas A&M University, we are developing a small fusion reactor (dense plasma focus) for use in subcritical nuclear assemblies.

Subsurface detection thermal signatures


Along with Dr. Handler at Texas A&M University, we are investigating wakes of underwater objects and their surface thermal signature.
