Pressure dialog box (ANSYS)

Type
Type	Specifies how the pressure load is defined.Normal pressure on 2D elements or 3D element faces: Defines a pressure load that is normal to element faces.Normal pressure on 2D elements or 3D element faces – spatial: Defines a pressure load by directly mapping a field to a global or local coordinate system.Components: Defines a pressure load in terms of a global or local coordinate system. For example, if you choose a local Cartesian coordinate system, you can enter pressure magnitude for each of the X, Y, and Z components.On 2D Solid Elements (Normal to Edge) XY: Defines a pressure load normal to the edges of elements in the axisymmetric XY plane. This option distributes the pressure to both sides of all elements that share the edge. Note: You can use this option to apply pressure only to planar elements (PLANE182, PLANE183), general axisymmetric elements (SOLID272, SOLID273) and shell elements (SHELL181, SHELL281).You can apply pressure only to the edges in the XY plane for SOLID272, SOLID273, SHELL181, and SHELL182 elements. You cannot apply edge pressures outside of the XY plane.Components – spatial: Defines a pressure load by directly mapping a field to a global or local coordinate system.On beams: Defines a pressure load on 1D elements in terms of either the global or the element coordinate system.On beams – spatial: Defines a pressure load by directly mapping a field to a global or local coordinate system.
Destination Folder
Load Container	Specifies the folder in the Simulation Navigator in which the boundary condition will be stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager	Displays a hierarchical listing of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Group Reference	Lets you apply the pressure load to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry or FE entities on which the load will be applied. ExcludedLets you remove individual entities from within your selected object.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Magnitude
Appears when Type is set to Normal on 2D elements or 3D element faces, Normal on 2D elements or 3D element faces – spatial, On beams, or On beams – spatial.
Pressure (normal pressure)VALI (on beam pressure)	Specifies the magnitude of the pressure load. For more information, see Additional magnitude options.
Direction
Appears when Type is set to Components or Components – spatial.
CSYS	Sets the coordinate system used to apply the pressure load.Global: Uses the global coordinate system.Cartesian: Lets you create or select a local Cartesian coordinate system.Cylindrical: Lets you create or select a local cylindrical coordinate system.Spherical: Lets you create or select a local spherical coordinate system.
Local CSYS	Appears when CSYS is set to anything other than Global.Lets you create or select a local coordinate system.For more information, see CSYS dialog box.
Components
Appears when Type is set to Components or Components – spatial.
Magnitude	Specifies the magnitude of the pressure load.
Px, Py, P****Pr, Pt, Pz****Pr, Pt, Pp	Specifies the pressure magnitude for each component. For more information, see Additional magnitude options.The available components depend on the coordinate system type.
Specify Field	Lets you select or define a field to define the pressure magnitude.
Scale Factors	Appears when Type is set to Field.For each component, specifies the scale factor to apply to the field.The components available depend on the coordinate system type.
Distribution
Appears when Type is set to a non-spatial pressure.
Method	Defines how the pressure load is distributed over the selected objects.Constant: Applies the magnitude to the object as a constant value.Spatial: Uses a unitless field to map the pressure load to the elements.A field is always mapped to global or Cartesian coordinates, even if it was defined in cylindrical, or spherical coordinates.
Distribution Field
Appears when Method is set to Spatial.
Specify Field	Defines how the pressure load is distributed over the elements in the selected area.
SURF154
Appears when Type is set to Components.
Automatic Creation of Surface Effect Elements	Controls whether the software creates surface effect element automatically when you export your ANSYS input file. If you clear this check box, you can manually create the surface effect elements in the FEM file.For more information, see Working with ANSYS surface effect elements.
Keyopts	Lets you specify the KEYOPTS modeling object to use for the surface effect elements.
Real Constants	Lets you specify the real constants modeling object to use for the surface effect elements.
Card Name	Displays the name of the solver card for the load.
