• Design and modeling of brake panels

• Automation of the repetitive tasks in Hypermesh

• User macro development in Hypermesh




• Design and modelig of brake panels


Layout information for the design of piping system



Modeling of piping

• Pro/e piping modul

• Existing documentation of piping



Connecting of devices

Point masses connected by RBE3 elements




Photo of the piping

CAD model of the piping

Finite element model



Automation of the repetitive tasks in Hypermesh

Geometry input from Pro/e

• Eliminating fittings from the Pro/e geometry

• Generating and cleaning middle surfaces

• Connecting pipe mesh to the base panel of the chassis

Routing of the pipe centerlines based on existing photo documentation

• Simple routing between two points

• Modification of existing centerlines

• Step by step routing

In both cases

• Importing device mass and inertia data from Pro/e export file



User macro development in Hypermesh

Simple centerline routing and modification

Cleaning of middle surface geometry

Connecting pipes to the chassis
