In situ research and measurements will restrict problems and direct solutions. Dedicated instruments such as a 2 cannel FFT analyser for noise and vibrations are available. 

Problems are controlled by the translation of the physics into relevant formulas. Appropriate level of accuracy is used ranging from rules of thumb, dedicated spreadsheets, and expert computer programs such as Finite Element Models  (FEMAP) for strength and Computational Fluid Dynamics (CFdesign and SPL Comflo) for fluid calculations.

Dedicated courses are provided for the various specialisations to ensure that solutions stick.

    Since April 2002 you can use the expert knowledge of SasTech.
