ESPL: CAE Solutions

Working Principle

ESPL: Working Principle

Many basic questions arise in the minds of ESPL engineers while working on the challenging CAE assignments. As the name itself suggests, Computer Aided Engineering, CAE process is greatly aided by the use of computers. But nevertheless, strong engineering basics becomes a vital factor for any engineer working on CAE assignment for getting the best results.

“We are engineers first & not just CAE tool operators”. This is our working principle and with this approach, we have developed expertise in different areas of CAE. Questioning the CAE assignment with the 4W + H in order to meet the results and customer expectation.

Execution Steps:

  • Understand Customer’s simulation requirements
  • Analyze those requirements from Design Engineering Perspective
  • Simulate
  • Optimize product/ process
