The Drop Test Manager is an automated solution that allows you to either simulate a single drop test or a choice of multiple iterations with the aim of finding the sensitivity of process variables like initial orientation and drop height in a typical drop test by controlling the run parameters and conditions with ease.
Many essential utility tools using HyperWorks-Tcl have been developed over the years to support Aerospace customers. A few tools have been collected and upgraded to be compatible with this release.
Solver interfaces supported in Engineering Solutions.
A solver interface is made up of a template and a FE-input reader.
Collectors are named organizational containers for collected entities. Collected entities are nameless entities which must reside within one, and only one, collector. Collected entities are mutually exclusive to a collector.
Entities which are given a name but are not collected or organized into containers.
Accelerometer entities measure acceleration in the simulation.
Ale Fsi Projection entities provide a coupling method for simulating the interaction between a Lagrangian material set (structure) and ALE material set (fluid).
Ale Reference System Curve entities defines a motion and/or a deformation prescribed for a geometric entity, where a geometric entity may be any part, part set, node set, or segment set.
Ale Reference System Group entities used to associate a geometric entity to a reference system type.
Ale Reference System Node entities defines a group of nodes that control the motion of an ALE mesh.
Ale Reference System Switch entities allows for the time-dependent switches between different types of reference systems, that is, switching to multiple PRTYPEs at different times during the simulation.
Ale Smoothing entities constraint keeps an ALE secondary node at its initial parametric location along a line between two other ALE nodes.
Ale Tank Test keyword provides curve through an engineering approximation when control volume airbags only require two engineering curves to define gas inflator and those two curves can be experimentally measured but the ALE inflator needs one additional state variable - the inlet gas velocity which is impractical to obtain.
