- The majority of the classifieds do not ask for the engineering skills; they ask for the formal knowledge of the accepted tools. Computational Fluid Dynamics ( CFD), for instance, is a method of solving the Navier- Stokes equations of the moving fluid and as such can be performed by using many different tools. FLUENT is one of such tools. The classified though would much more frequently ask for the knowledge of FLUENT than for the experience in CFD. That seems practical; the employer had adopted FLIUENT as a tool and wants someone to use it. At the same time, the employer does not ask for a capability of understanding where FLUENT should be used and where --not. In sorts the employer would have published a request for a monkey which had been taught how to push certain buttons.
There is a legend on how Albert Einstein was admitted to the US. Among other things he had to answer some trivial questions:
- What is the capital of the state of Alabama?
- I don't remember,- said Albert, "but I am sure that the geographical atlas has this info."
- Where is the Mason- Dixon line?
- I don't remember,- said Albert, "but I am sure that the book on the US history has this info."
And so on and so on. Einstein sincerely did not understand why a person would remember such things; his point of view was that a person should know where to find such information if needed. I echo him; it is unlikely that medieval knights could memorize what was the Holy Grail but they sure as Hell knew where to go to find it. That is the way a true man thinks- he tries to maintain the path and the goal, not the means and reference points.
So if someone comes to me and tells me that he/she knows FLUENT I would simply ask this person to explain to me if he/she could solve the problem without it. That brings us to the Golden Gate bridge.
