About midas FX+ for DIANA
midas FX+
is a general purpose pre/post-processor for CAE simulation. midas FX+ has been specialized for civil/architectural applications.
DIANA is the expert finite element analysis system for non-linear anddetailed simulation for civil/architectural applications with special emphasison Earthquake Analysis of RC structures.
midas FX+ for DIANA (FX4D) is a customized version of midas FX+.
FX4D has been developed for DIANA by strategic & technical alliancebetween MIDAS IT and TNO DIANA.
FX4D is an official pre/post-processor for DIANA, designed by TNO DIANAand developed by MIDAS IT.
Strategic Al liance between MIDAS IT and TNO DIANA (2005)
