What's New

Speed improvement for FLEX_BODY (FORTAN only)

The computational efficiency in the FLEX_BODY element has significantly improved in the 2003 release. The improvement is obvious in all models that have flexible bodies. The most dramatic improvement is with flexible bodies that have high numbers of selected modes (such as SELMOD in .mtx file).

In an extreme case of a model dominated by a large FLEX_BODY that has 288 modes, the simulation times improved by 6.1 times. The improvements seen in a typical model are more modest, about 5-10%, and vary depending on how much the FLEX_BODY dominates the solution and how many enabled modes are in the FLEX_BODY. This change has no effect on the numerical results of the simulation.

Changes

Zeroing out tiny values in REQUEST (FORTAN only)

Any REQUEST (or REQSUB) containing expressions now have their values set to zero when the magnitude is less than 1.0E-14.
