VTM standalone


The VTM (Vehicle Trim Modeler) Standalone solver is ideally suited for modeling the low frequency response of poroelastic materials.  VTM includes advanced poroelastic finite element formulations and robust projection algorithms for fully coupling structural, fluid and poroelastic domains.  The VTM solver can also be easily integrated into existing Nastran solution processes.
