‘The 80/20 Criteria for the SUCCESSFUL Implementation of CFD/CAE within the Design Process…’

The Pareto Principle or 80/20 rule states that for many events eighty per cent of the effects come from twenty percent of the causes. For example, in economics the richest twenty percent of the population earns eighty percent of the overall income. In the product development world eighty per cent of the product performance or project success is often dictated within the first twenty per cent of the development life-cycle. However, to what extent can this also applied to the Computer Aided Engineering (CAE) world? Is eighty per cent of the business value delivered associated with only twenty per cent of the resources deployed, or time spent using simulation technology?
If this is the case, it is time for engineering companies to consider what are the obstacles preventing successful implementation of CAE tools within their design process? 80/20 Engineering believe that when a product development group is looking to realize the benefits of computational simulation, there are seven areas of the implementation that need detailed assessment. We refer to these as the ’80/20 Criteria for SUCCESS’: -
With all these potential obstacles in the path of a successful implementation of a design focused CFD/CAE strategy, is it still worth the investment of time and money? Our opinion is “YES, ABSOLUTELY” because once the technology is SUCCESSFULLY implemented significant prototype cost savings and quality improvements become a standard part of the design process. The important point is to recognise what potential implementation barriers exist early-on and make sure there are plans in place to overcome the issues as they occur.
Of the seven criteria mentioned above the first four are best addressed through planned training and adequate education. Both formal training courses and one to one mentoring with experienced engineers are recommended. By ‘experienced engineers’ we mean those who have seen many other companies go through a SUCCESSFUL design based implementation process many times before. Only these engineers will have the knowledge to understand what is happening when simulation results do not exactly match experimental data.
If computer resources are identified as a potential issue then partnering with an organization which can provide access to fast high performance computing clusters could be an answer, to overcome the bottleneck. However, an assessment of the CFD technology in use would also be our recommendation.
Unusual Fluid Dynamics or Complex Physics are best addressed by also partnering with an organization that is able to offer design focused solutions whilst providing access to advanced high-end consultancy services. Many companies find this very economical, particularly if their unusual or more difficult applications are only a small part of the potential benefit CFD will bring to their design, research and development efforts.
