Replicating the cosmos with CAD
Designers of a superlarge planetarium transferred data from an astronomy program into their CAD software as a means of locating 4,000 stars on a dome's surface.
Rapid prototyping gets even faster
Most rapidprototype facilities can turn around a quote and a model in about a week.
Preparing for a Fluid Simulation
CFD software is easier to use, faster, and more effective.
New element lops time off CFD simulations
"CFD simulations are finite-volume based, so the solver calculates mass, momentum and energy fluxes through the surface of these control volumes," says CD-adapco Vice President Dennis Nagy.
Maintenance manuals go interactive
Imagine a maintenance manual that helps diagnose problems and then guides you through repairs with vivid color animations.
FEA lets compactor roll on polygons
Compaction equipment manufacturer Bomag GmbH & Co. in Germany used FEA software to analyze and optimize the polygonal rollers on the company's recently developed earth compactors.
Solid ideas improve fluid simulations
Fluid-flow problems usually involve structures and more frequently, heat transfer.
Customizing to order
How to respond when customers demand more personalized products, better customer service, and instant feedback on orders.
Chevrolet HHR
Most everyone who saw the HHR was quick to remark," Oh, it's like a PT Cruiser."
PLM helps price plastic parts
Precision plastic parts maker Montaplast, Morsbach, Germany, costs new projects with a PLM (product-life-cycle management) shared database.
Mechanical design software for modeling
SolidWorks 3D mechanical-engineering software lets users quickly build solid models with familiar drag-and-drop, pointand-click, and cut-and-paste functions.
Sneaking up on a solution
Analyzing a structure subjected to nonlinear, transient, dynamic, and impact loading is a major league task.
New e-format for price quotes
The Power Transmission Distributors Association (PTDA) and the Bearing Specialists Association have devised a new standard template for electronic transmission of manufacturer price and product updates.
A smarter CAD alternative
A "smart," easy-to-use, 3D-surface solid-modeling software lets industrial designers be more creative.
Start here when simulating rubber and foams
Little-known features in FEA software convert test data into inputs for simulating hyperelastic materials.
