Slide 1

Dr. Hell Consulting and Engineering Dr. Hell Consulting and Engineering and Adam Hodgson Engineering: I-DEAS and ADINA in non-direct auxiliary Finite Element and CFD-examination Presented by Dr. Ulrich Heck Dr. Ulrich Heck

Slide 2

Dr. Hell Consulting and Engineering Presentation UG-User 2004 Background The FE-solver program ADINA will be implanted into NX NASTRAN to end up the non-direct solver for auxiliary examination Our business Our needs Our apparatuses Our experience Dr. Ulrich Heck

Slide 3

Dr. Hell Consulting and Engineering Structural Analysis CFD (Computational Fluid Dynamics) O-Ring Compression Karman vortex road Heat Transfer FSI (Fluid-Structure-Interaction) Frictional Heating (Brake) Vortex incited vibrations Our business: Engineering administrations Dr. Ulrich Heck

Slide 4

Dr. Hell Consulting and Engineering Our needs – client\'s requests Our main goal : Quickly accomplish astounding results for extremely complex issues 1. Introductory undertaking: Calculate exertion for lattice and taking care of the issue Meshing Needs Time for cross section - >more a specialty than a workmanship Generating astounding cross sections from poor CAD-information (imported models) Various choices to accomplish the outcome: Optimize/repair the CAD information or cross section on existing CAD information Manual lattice, consolidating models and so on. Dependable and strong Solver Needs: One CAE-Solvers for an extensive variety of complex issues Reliable and hearty Universally relevant techniques Solving in sensible time without super PC Dr. Ulrich Heck

Slide 5

Dr. Hell Consulting and Engineering Flow with conduction Flow with radiation Thermo-mechanical coupling Heat exchange Conduction Radiation Convection ADINA (FEM) Finite Volume CFD-Solver Fluent Our devices Solver CFD Complex turbulent Highly compressible (stuns) Turbulent warmth exchange Multiphase Large issues (turbulent 2 Mio Cells) Non-lin auxiliary Contact Nonlinear Material (plastics, elastic) Large (plastic) strain extensive relocation CFD laminar turbulent Transient/unfaltering state moving cross sections moderate size FSI Transient, profoundly coupled Static stream incited vast misshapening or strains Dr. Ulrich Heck

Slide 6

Dr. Hell Consulting and Engineering I-deas is utilized for: All CAD-Modeling including geometry import and repairing poor CAD models Meshing abilities of I-deas Mapped/Free Meshing Section Meshing Manual Meshing All cross sections for ADINA (auxiliary, CFD, heat-exchange, FSI) Special CFD network components are utilized for complex CFD (Fluent) - > TGrid: Use I-deas hexahedral or surface lattice (triangular), Merge network locales for half and half "gooey" lattice Mesh tetrahedral volume in TGrid Our cross section apparatuses Dr. Ulrich Heck

Slide 7

Dr. Hell Consulting and Engineering Tools conclusion Quickly accomplish astounding results for exceptionally complex issues I-deas Focal device for CAD-demonstrating and coinciding Covers our over all requirements for lattice Only abnormal state CFD displaying requests other matrix generators ADINA Covers our requirements for a wide range of issues One framework to take care of this extensive variety of issues ADINA/I-deas in mix are the center devices for our every day work Dr. Ulrich Heck

Slide 8

Dr. Hell Consulting and Engineering Present framework: TRANSOR is ADINA/I-deas interface depends on widespread records Runs ADINA in foundation Imports comes about documents by means of general document interpreter ADINA/I-deas/NX-Nastran Our experience: 6 Years with ADINA/I-deas required changes in NX-NASTRAN: Simplified exchange of geometry data (e.g. component introduction contact surfaces, 2d models… ) Post preparing: direct show comes about Ease of utilization Long term desirables: Easier versatile lattice Topology improvement - > new CAD Model Dr. Ulrich Heck

Slide 9

Dr. Hell Consulting and Engineering Examples Some cases like client ventures, pre-ponders, own confirmation issues Even if ADINA is a dependable, strong device, setting up experiments is an absolute necessity when working with new sorts of issues Collect involvement with the issue sorts Check the plausibility (accessible models, equipment power and so on.) Check impact of demonstrating parameters (lattice, time venturing and so on.) enhance nature of results: Compare numerical results with trial information Advantages of ADINA System: Universally material strategies ADINA propose the right understanding technique, component plan and so forth (e.g. consequently changes to u/p-plan if there should be an occurrence of incompressible material) Gives clues if no arrangement is achieved ADINA client bolster Excellent bolster Works while you rest Never been frustrated by the outcomes ADINA give us Very fulfilled clients ! Dr. Ulrich Heck
