Proprietary1OverviewA common need is to take the Output from analysis A and map that data as Input to analysis B. This ability has been present in WB since V12(1 way FSI) but has been greatly enhanced in V13:Introduction of a new External Data system to import loads from 3rd party applicationsThermal-Stress Analysis inside Mechanical using different models(meshes)Schematic support for 1-way Load transfer between Mechanical and Electronic systems(HFSS/Maxwell)Volumetric temperature transfer between CFD and Mechanical 2009 ANSYS, Inc.

Proprietary3External Data OverviewOften users will have data from other applications they wish to map into their Mechanical AnalysisThis feature is available through a new Component system called External Data which can transfer loads into the Mechanical Setup CellCapabilities include: Pressure, Temperature, Convection, and Displacement(Beta)2D edges, 3D Faces, Volumetric(for temperature)Variety of mapping options including mapping from 2D to 3D (e.g. 2D axisymmetric to 3D solid)

This is very helpful to verify units and transformations are correctIf Source Data is 2D and target is 3D option to display the projection planeOption to hide source points falling inside the target model. Useful to remove clutter from volumetric mapping plots

Thermal-Stress Analysis with Different ModelThis feature allows for:Changing meshDifferent body setOther model difference including contact, geometry, etc. 2009 ANSYS, Inc. All rights reserved.#ANSYS, Inc. ProprietaryThermal-Stress Analysis with Different Model

An Automatic method is employed by default to match the source and target bodies based on a heuristic of volume and centroid. This prevents bleeding of mapping from 1 body to another.Same mapping controls used for External Data
