Mesh of the Golden Gate Bridge

Data for this model was obtained from the book published by the Golden Gate Bridge and Highway District - 1987. This is a reprint of the "Report of the Chief Engineer to the Board of Directors of the Golden Gate Bridge Highway District" - September 1937. This mesh was originally constructed in the mid-1990's and, as such, was too large to be analyzed at that time. This model is for display purposes only.

Gas Piston and Rod Low Denisty
This version of the model has 7,488 nodes,
271 shells, and 3,560 bricks in 9 parts.

Gas Piston and Rod High Density
This version of the model has 136,045 nodes,
1085 shells, and 105,358 bricks in 9 parts.

National Ignition Facility Chamber

The laser target chamber consists of an aluminum inner shell, a concrete outer shell, and aluminum ports through which laser beams are delivered. This model was built by Wayne Miller at the Lawrence Livermore National Laboratory.

Quarter Of Finite Element Mesh of Child Proof Cap

This child proof cap was modeled with hexahedral elements. The geometry was built in a solids modeler. The helical thread was easily modeled, with mesh lines which transition from inner radius to outer radius, using the projection method.

CloroxTM Clean-up® Bottle

The geometry for this bottle was designed in Pro/E®. It has 82 trimmed surfaces. These surfaces form a composite surface in TrueGrid®. The shell mesh is then smoothly distributed across the composite surface.

Meshof a Full Size Pick-up Truck Frame

Analysis model developed by TransMotive Technologies, Inc., Santa Rosa, CA, using TrueGrid®. This model was used by TransMotive Technologies, Inc. for both crashworthiness analysis as well as structural durability studies.

Mesh of An Impactor

This mesh was created by Sachin P. Budhabhatti for educational purposes.

Mesh of a Dam

This model was built by Mike Burger for the Bureau of Reclamation. The terrain (in green), the foundation of the dam (in red), and the water behind the dam (in blue), are all captured in this model.

Mesh of a Racing Bike

Analysis model developed by TransMotive Technologies, Inc., Santa Rosa, CA, using TrueGrid®. This model was used by TransMotive Technologies, Inc. to do a nonlinear dynamic impact simulation. The mesh lines have beem removed from the overall model because there are too many mesh lines to distinguish at this distance. The fine detail of this mesh can be seen in the zoomed-in images.

Hexahedral Mesh of a Tool Bracket

This simple model is constructed with three parts. The geometry consists of 10 surfaces built in TrueGrid®. There are 23,217 nodes and 17,502 brick elements. The quality of the mesh is completely under the control of the user.

Finite Element Mesh of a Fictitious Starship

This model of a toy can be used to determine it's durability. It is constructed of all hexahedral brick elements, most of which are nearly orthogonal. The geometry was constructed in TrueGrid®. There are 10 parts. They form one contiguous model. The upper face of the disc forms a classic butterfly block mesh construction which was then smoothed using the elliptic solver.

Finite Element Mesh of a Pipe Elbow

The base of this part is done in a quarter section and then replicated. There are 3 separate parts to this model. There are 1,440 nodes that merge out. There remain 20,844 nodes and 16,000 bricks.

Finite Element Mesh of a Rim

This single part has a shell stiffener down the middle. There are 16,575 nodes, 3,104 shells, and 6,208 bricks in this model.

Mesh of a Wheel Hub

This mesh is constructed from two simple parts. The first part is replicated 20 times. The second part is replicated 16 times. The outer surface is parametric and can be switched by changing one command. 16 surfaces are needed for this mesh: 7 cylinders, 3 tori, 1 extruded 2D curve, and 4 planes. All the surfaces for this model are built in TrueGrid®.
