Nodal Pressure dialog box (Simcenter Nastran/Simcenter Samcef)

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.
Type
Does not appear when the analysis type is axisymmetric structural.
Type	Specifies how the pressure load is defined.Normal Pressure on 2D or 3D Element Corner Nodes: Defines a pressure load that is applied normal to the corner nodes of 2D elements or the corner nodes of the faces of 3D elements.If you use a spatially varying field or expression to define the magnitude of the pressure load, Simcenter 3D evaluates the intensity of the pressure load at each node of the 2D element or the 3D element face and writes it to the P1, P2, P3, and P4 fields of the PLOAD4 bulk entry.Components: Defines a nodal 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.If you use a spatially varying field or expression to define the magnitude of the pressure load, Simcenter 3D evaluates the intensity of the pressure load at each node of the 2D element or the 3D element face and writes it to the P1, P2, P3, and P4 fields of the PLOAD4 bulk entry.Corner Node ID Table-Pressure: Defines varying pressure values at the nodes identified in the node ID table. A node ID table contains a list of node IDs and corresponding scale factors for each nodal component (X,Y,Z). For each node in the node ID table, the load magnitude at the component is multiplied by the scale factor.Corner Node ID Table-Normal Pressure: Defines varying pressure values that are applied normal to the nodes identified in the node ID table. A node ID table contains a list of node IDs and corresponding scale factors for each nodal component (X,Y,Z). For each node in the node ID table, the load magnitude at the component is multiplied by the scale factor.Note: Spatial boundary conditions are best when you want to use externally generated results or other data to define the load.
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. Use the options in the Excluded group to remove individual entities from within your selection.
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
Pressure	Appears when Type is set to Normal Pressure on 2D or 3D Element Corner Nodes, Corner Node ID Table-Pressure, or Corner Node ID Table-Normal Pressure.Specifies the magnitude of the pressure load.For more information, see Additional magnitude options.
Normal Pressure Along Edge	Appears when the solver is Simcenter Nastran or Simcenter 3D Multiphysics and the analysis type is axisymmetric structural.Specifies the magnitude of the pressure load that acts in the axisymmetric plane normal to element edges.For more information, see Additional magnitude options.
Shear Pressure	Appears when the nodal pressure load is created by importing a Simcenter Nastran or Simcenter 3D Multiphysics input file that contains PLOADE1 and PLOADX1 bulk entries.Specifies the magnitude of the normal component of the surface traction.For more information, see Additional magnitude options.
In Plane Pressure	Appears when the nodal pressure load is created by importing a Simcenter Nastran or Simcenter 3D Multiphysics input file that contains PLOADE1 and PLOADX1 bulk entries.Specifies the magnitude of the in-plane component of the surface traction.For more information, see Additional magnitude options.
Direction
Appears when Type is set to Components or Corner Node ID Table-Pressure.
CSYS	Sets the coordinate system that the software uses to apply the pressure load. You can select the Global Cyclic Analysis or the Global coordinate system, or you can create one of the following types of local coordinate systems: Cartesian, Cylindrical, Spherical.Note: The Global Cyclic Analysis coordinate system is available only if it is defined in the FEM.
Local CSYS	Appears when CSYS is set to Cartesian, Cylindrical, Spherical.Lets you create or select a local coordinate system.For more information, see CSYS dialog box.
Components
Appears when Type is set to Components .
Magnitude	Specifies the magnitude of the pressure load.
Px, Py, Pz****Pr, Pt, Pz****Pr, Pt, Pp	Appears when Magnitude is set to Expressions.Specifies the pressure magnitude for each component. The available components depend on the coordinate system type.
Specify Field	Appears when Magnitude is set to Field.Lets you select or define a field to define pressure magnitude.
Scale Factors	Appears when Magnitude is set to Field.Specifies the scale factor to apply to the field for each component.The available components depend on the coordinate system type.
Scaling ID Table
Appears when Type is set to Corner Node ID Table-Pressure or Corner Node ID Table-Normal Pressure.
Specify Field	Defines how the pressure load is distributed over the elements in the selected area.
Card Name	Displays the name of the corresponding solver bulk entry or command.
