Loads and Boundary Condition Options

© 2011 ANSYS, Inc. June 21, 2012 22

Applying Loads to Nodes

“Nodal orientation” allows users to assign a coordinate system to node or nodal sets

Direct FE loads and boundary conditions can be applied to selected nodes, whose direction is defined by “Nodal orientation”

Nodes are oriented in cylindrical system for loads and boundary condition definitions

Electromagnetic-Structure Coupling

Magnetics forces will induce stresses(Example: Motor)

Resistive losses will cause thermal stress(Example: Satellite Dish Antenna)

Electromagnetic-Fluid-Structure Coupling • Maxwell+Fluent

– One-way and two-way β coupling

• Combine with 1-way FSI

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.

Supported Data Types

© 2011 ANSYS, Inc. June 21, 2012 39

Importing Multiple Files

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

© 2011 ANSYS, Inc. June 21, 2012 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

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

# 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")
