Mapdl.etable(lab='', item='', comp='', option='', **kwargs)#

Fills a table of element values for further processing.

Mechanical APDL Command: ETABLE

Parameters:

labstr

Any unique user-defined label for use in subsequent commands and output headings. A valid label has a maximum of eight characters and is not a general predefined Item label. Default: An eight- character label formed by concatenating the first four characters of the Item and Comp labels.

If the same as a previous user label, the result item is included under the same label. Up to 200 different labels can be defined.

The following predefined labels are reserved:

• REFL - Refills all tables previously defined with the etable commands (not the calc module commands) according to the latest etable specifications. It is convenient for refilling tables after the load step ( Set displays ) has changed. Remaining fields are ignored.

• STAT - Displays stored table values.

• ERAS - Erases the entire table.

itemstr

Label identifying the item. General item labels are shown in the tables below. Some items also require a component label. Character parameters are valid. Item = ERAS erases a Lab column.

compstr

Component of the item (if required). General component labels are shown in the tables below. Character parameters can be used.

optionstr

Option for storing element table data:

• MIN - Store minimum element nodal value of the specified item component.

• MAX - Store maximum element nodal value of the specified item component.

• AVG - Store averaged element centroid value of the specified item component (default).

Notes

etable defines a table of values per element (the element table) for use in further processing. The element table is organized similar to a spreadsheet, with rows representing all selected elements and columns consisting of result items which have been moved into the table ( Item, Comp ) via etable. Each column of data is identified by a user-defined label ( Lab ) for listings and displays.

After entering the data into the element table, you are not limited to listing or displaying your data ( plesol, presol, etc.). You can also perform many types of operations on your data, such as adding or multiplying columns ( sadd, smult ), defining allowable stresses for safety calculations ( sallow ), or multiplying one column by another ( smult ). For more information, see Getting Started

For reinforcing elements, this command displays the results of reinforcing member (individual reinforcing) selected via the layer, N command (where N is a given reinforcing member). layer,0 (default) or layer,1 selects the first reinforcing member.

Various results data can be stored in the element table. For example, many items for an element are inherently single-valued (one value per element). The single-valued items include: SERR, SDSG, TERR, TDSG, SENE, TENE, KENE, ASENE, PSENE, AKENE, PKENE, DENE, WEXT, AENE, JHEAT, JS, VOLU, and CENT. All other items are multivalued (varying over the element, such that there is a different value at each node). Because only one value is stored in the element table per element, an average value (based on the number of contributing nodes) is calculated for multivalued items. Exceptions to this averaging procedure are FMAG and all element force items, which represent the sum only of the contributing nodal values.

Two methods of data access can be used with the etable command. The method you select depends upon the type of data that you want to store. Some results can be accessed via a generic label (Component Name method), while others require a label and number (Sequence Number method).

The component name method is used to access the general element data (that is, element data which is generally available to most element types or groups of element types). All of the single-valued items and some of the more general multivalued items are accessible with the Component Name method. Various element results depend on the calculation method and the selected results location ( avprin, rsys, layer, shell, and esel ).

Although nodal data is readily available for listing and display ( prnsol, plnsol ) without using the element table, you can also use the Component Name method to enter these results into the element table for further “worksheet” manipulation. (See Getting Started Item and Comp labels for the component name method is shown in ETABLE - General Result Item and Component Labels. See ETABLE - Selected Result Component Labels for a list of selected result ( Item = SRES) Comp labels.

The sequence number method enables you to view results for data that is not averaged (such as pressures at nodes, temperatures at integration points, etc.), or data that is not easily described in a generic fashion (such as all derived data for structural line elements and contact elements, all derived data for thermal line elements, layer data for layered elements, etc.). A table illustrating the Items (such as LS, LEPEL, LEPTH, SMISC, NMISC, SURF, etc.) and corresponding sequence numbers for each element is shown in the Output Data section of each element description.

Some element table data are reported in the results coordinate system. These include all component results (for example, UX, UY, etc.; SX, SY, etc.). The solution writes component results in the database and on the results file in the solution coordinate system. When you issue the etable command, these results are then transformed into the results coordinate system ( rsys ) before being stored in the element table. The default results coordinate system is global Cartesian ( rsys,0). All other data are retrieved from the database and stored in the element table with no coordinate transformation.

To display the stored table values, issue the pretab, pletab, or etable,STAT command. To erase the entire table, issue etable,ERAS. To erase a Lab column, issue etable, Lab,ERAS.

When the GUI is enabled, if a Delete operation in a Define Element Table Data dialog box writes this command to a log file ( Jobname.LOG or Jobname.LGW ), the program sets Lab = blank, Item = ERASE, and Comp = an integer number. In this case, the program has assigned a value of Comp that corresponds to the location of a chosen variable name in the dialog list. It is not intended that you type in such a location value for Comp in a session; however, a file that contains a GUI-generated etable command of this form can be used for batch input or the input command.

The MIN and MAX options are not available for thermal elements.

The element table data option ( Option ) is not available for all output items. See the table below for supported items.
