Selecting the Nodal Output Variables
The nodal variables that can be written to the output database are defined in Nodal Variables (Abaqus/Standard) and Nodal Variables (Abaqus/Explicit).

Selecting the Nodes for Which Output Is RequiredFor history output you must specify the node set (or, in Abaqus/Explicit, the tracer set) for which output is being requested. For field output the specification of the node set or tracer set is optional; if you do not specify a node set or tracer set, the output will be written for all the nodes in the model. Requesting Field Output for the Exterior Nodes in the ModelYou can select output on the node set consisting of all the exterior nodes in the model. This node set is generated internally by Abaqus and includes all the nodes that belong to the exterior three-dimensional elements. Controlling the Output FrequencyThe frequency of nodal output is controlled as described in Controlling the Frequency of Output to the Output Database. Controlling the Precision of Nodal OutputThe precision of nodal output is controlled as described in Controlling the Precision of Element and Nodal Output. Requesting Preselected OutputYou can request the preselected, procedure-specific nodal output variables described in Preselected Output Requests. In this case you can specify additional variables as part of the output request. Alternatively, you can request all nodal variables applicable to the current procedure type. In this case any additional variables you specify are ignored. Specifying the Directions for Nodal Field OutputFor nodal variables 1, 2, and 3 refer to the global directions X, Y, and Z, respectively. For axisymmetric elements 1 and 2 refer to the global directions r and z. Nodal field results are written to the output database in the global directions. If a local coordinate system is defined at a node (see Transformed Coordinate Systems), the local nodal transformations are written to the output database as well. You can apply these transformations to the results in the Visualization module of Abaqus/CAE to view components in the local systems. Specifying the Directions for Nodal History OutputFor nodal variables 1, 2, and 3 refer to the global directions X, Y, and Z, respectively. For axisymmetric elements 1 and 2 refer to the global directions r and z. Nodal history results are written to the output database in the global directions unless a local coordinate system has been defined at a node (see Transformed Coordinate Systems). In this case you can specify whether output is desired in global or local directions. Obtaining Nodal History Output in the Global DirectionsYou can request vector-valued nodal variables in the global directions, which is the default for nodal history output requests to the output database since most postprocessors assume that components are given in the global system. Obtaining Nodal History Output in the Local Directions Defined by Nodal TransformationsYou can request vector-valued nodal variables in the local directions defined by nodal transformations. Visualizing Boundary ConditionsBoundary conditions can be visualized in the Visualization module of Abaqus/CAE by selecting . Click the Entity Display tab in the dialog box that appears. In an Abaqus/Standard analysis boundary condition information is written to the output database only when some nodal output variables are requested as field output. |
