StressCheck's implementation of numerical simulation is designed to support solution verification, an essential technical requirement of Simulation Governance. The implementation makes it possible to encapsulate complexity, improve productivity, contain costs, and ensure the reliability of results for the expert simulation analyst as well as the non-FEA expert DaDT engineer.]]>

]]> White Paper: The Case for Simulation Governance https://www.esrd.com/resource-library/product/white-paper-the-case-for-simulation-governance/ Mon, 03 May 2021 18:10:16 +0000 https://www.esrd.com/?post_type=product&p=20904 All major engineering organizations use numerical simulation in support of decisions pertaining to design and design certification. The question of how well numerical simulation is managed is being addressed by the various stakeholders with increasing urgency. It is now generally recognized that numerical simulation, properly managed, can be a major corporate asset but poorly managed, or not managed at all, can become a major corporate liability.]]>
