32 Coupling Physics Approach Reality 32

33 ANSYS Solution for Multiphysics Electromagnetic Simulation Mechanical Simulation Computational Fluid Dynamics (CFD) Low Frequency Maxwell Simplorer High Frequency HFSS SIwave Implicit ANSYS Mechanical Explicit ANSYS Explicit ANSYS AUTODYN ANSYS LS-DYNA Electronics cooling ANSYS Icepak General CFD ANSYS CFD Fluid Dynamics Structural Mechanics Electromagnetics 33

34 Fluid-Structure Coupling 34

35 Electromagnetic-Structure Coupling Magnetics forces will induce stresses(example: Motor) Resistive losses will cause thermal stress(example: Satellite Dish Antenna) 35

36 Electromagnetic-Fluid-Structure Coupling Maxwell+Fluent One-way and two-way β coupling Combine with 1-way FSI β 36

37 External Data Mapping: Motivation Exchange files are frequently encountered to transfer quantities from one simulation to another. Efficient mapping of point cloud data is required to account for misalignment, non matching units or scaling issues. 37

38 Supported Data Types 38

39 Importing Multiple Files Multiple files can be imported for transient analyses or to handle different data to be mapped on multiple bodies 39

40 Validating the Mapped Data Visual tools have been implemented to control how well the data has been mapped onto the target structure Both the size of the spheres and their color provide indication of the mapping quality 40

42 ACT Introduction Application Customization Toolkit (New in R14.0) Encapsulate APDL macros: Allows re-use of legacy APDL-scripts and encourages migration from MAPDL to Mechanical via encapsulated macros MAPDL exposure: Fills the gap between MAPDL solver capabilities and their exposure in ANSYS Mechanical New pre-processing features (custom loads and boundary conditions) New post-processing features (custom results) 3rd party/in-house solver integration (Mechanical GUI) 42

43 Simple ACT Example! APDL_script_for_convection.inp! Input parameters: esel,s,type,,10 cm,component,elem thickness = film_coefficient = 200. temperature = APDL ANSYS Mechanical 43!

45 Customize Toolbar Using XML XML definition: <load internalname="convection on Blade" caption="convection on Blade" icon="convection" issupport="false" isload="true"> <version>1</version> <callbacks> <onsolve>convection_blade_computation</onsolve> </callbacks> <details> <property internalname="geometry" datatype="string" control="scoping"></property> <property internalname="thickness" caption="thickness" datatype="string" control="text"></property> <property internalname="film Coefficient" caption="film Coefficient" datatype="string" control="text"></property> <property internalname="ambient Temperature" caption="ambient Temperature" datatype="string" control="text"></property> </details> </load> 45

46 Define Internal Process Using Python Python script: # Get the scoped geometry: propgeo = result.getdpropertyfromname("geometry") refids = propgeo.value # Get the related mesh and create the component: for refid in refids: meshregion = mesh.meshregion(refid) elementids = meshregion.elements eid = aap.mesh.element[elementids[0]].id f.write("*get,ntyp,elem,"+eid.tostring()+",attr,type\n") f.write("esel,s,type,,ntyp \n cm,component,elem") # Get properties from the details view: propthick = load.getdpropertyfromname("thickness") thickness = propthick.value propcoef = load.getdpropertyfromname("film Coefficient") film_coefficient = propcoef.value proptemp = load.getdpropertyfromname("ambient Temperature") temperature = proptemp.value 46 # Insert the parameters for the APDL commands: f.write("thickness="+thickness.tostring()+"\n") f.write("film_coefficient="+film_coefficient.tostring()+"\n") f.write("temperature="+temperature.tostring()+"\n") # Reuse the legacy APDL macros: f.write("/input,apdl_script_for_convection.inp\n")

47 3 rd Party/In-house Solver Integration ACT allows partners/customers to seamlessly integrate into Mechanical Non parametric optimization solver (topological optimization) 47
