The more I look into complex technologies, the more I realize that they are often like adding salt on the existing mindset of the user. If the user is predisposed to "doing it the hard way", then the dish will taste bad. If they will adapt their underlying process and thinking a bit, the salt will make an exquisite dish out of the same ingredients. Using CAE for pre-test validation is usually worthless. But, that's what many engineering teams are used to with standard development processes based on lab/prototype verification. Using CAE to guide design is where the money is...

Using CAE for pre-test validation is usually worthless. But, that’s what many engineering teams are used to with standard development processes based on lab/prototype verification. Using CAE to guide design is where the money is…

Technology is exciting, until it forces a change in habits or perspective. As an engineering manager, I have in the past asked my product engineers to use simulation to guide design, not just look for pre-test validation. I also have worked with a few software companies that could change the idea that CAD, not some other software drives design. Afterall who cares what the CAD entity is called as long as you can create the shape you want. Should we be a slave to CAD features as named and defined in a particular CAD system. There may soon be a better way. Jeff,
