Altair Engineering (www.altair.com) and Ansoft Corporation (www.ansoft.com) have announced that the former's HarnessLink® wiring harness and system-design tools will be integrated with the latter's SIMPLORER® simulation software. The companies say that coupling will give automotive, aerospace, and marine manufacturers a complete design environment for electrical distribution systems. Among the promised benefits: shorter simulation time and earlier detection of problems. HarnessLink manages product options and harness variables. SIMPLORER analyzes electrical performance, heating of wires, and overall system analysis.
