Units for Finite Element Analyses
Back ground:
Finite element programs do not consider the units of given quantities , it is theuser's responsibility to ensure that the given numbers have consistent units. There arenumerous different sets of units that can be used when performing FE simulations. The bestset of units will depend on the problem , typically the most accurate results are obtainedif the units are chosen such that the values of the input quantities to the FE simulationare close to unity. By having the input quantities close to 1, the influence of round-offerrors and truncation errors are reduced.
