ECSS-E-ST-32-03 (Space engineering - Structural finite element models) defines the requirements for finite element models used in structural analysis. This Standard specifies the requirements to be met by the finite element models, the checks to be performed and the criteria to be fulfilled, in order to demonstrate model quality. The Standard applies to structural finite element models of space products including: launch vehicles, transfer vehicles, re-entry vehicles, spacecraft, landing probes and rovers, sounding rockets, payloads and instruments, and structural parts of all subsystems. This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00.
