in automobiles. As part of the project. NIST lias 

 developed a finite element simulation of the 

 mold filling process used to manufacture high 

 strength body components. In a similar manner, 

 NIST is developing process models and simula- 

 tions for robotic manufacturing operations and 

 production of powder metal particles. 



mechanics, stress analyses, and three-dimension- 

 al graphics and visualization techniques. 

 Advanced computing technology directly affects 

 the speed and level of detail that can be incorpo- 

 rated into the models, and therefore the realism 

 and benefits that can be obtained. 



Much of the ability to apply new theoretical 

 understanding depends on the performance and 

 cost of advanced computing technologies. 

 Process modeling and simulation draws heavily 

 on computationally intensive techniques in such 

 areas as heat transfer and solidification kinetics, 

 coupled fluid flow, finite difference appro.xinia- 

 tions, turbulent viscosity calculations, fracture
