ESEL, Type, Item, Comp, VMIN, VMAX, VINC, KABS
Selects a subset of elements.

Compatible Products: – | Pro | Premium | Enterprise | Ent PP | Ent Solver | DYNA


Label identifying the type of select:



Select a new set (default).



Reselect a set from the current set.



Additionally select a set and extend the current set.



Unselect a set from the current set.



Restore the full set.



Unselect the full set.



Invert the current set (selected becomes unselected and vice versa).



Display the current select status.

The following fields are used only with Type = S, R, A, or U:


Label identifying data, see Table 123: ESEL - Valid Item and Component Labels. Some items also require a component label. If Item = PICK (or simply “P”), graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). Defaults to ELEM. If Item = STRA (straightened), elements are selected whose midside nodes do not conform to the curved line or non-flat area on which they should lie. (Such elements are sometimes formed during volume meshing (VMESH) in an attempt to avoid excessive element distortion.) You should graphically examine any such elements to evaluate their possible effect on solution accuracy.


Component of the item (if required). Valid component labels are shown in Table 123: ESEL - Valid Item and Component Labels below.


Minimum value of item range. Ranges are element numbers, attribute numbers, load values, or result values as appropriate for the item. A component name (as specified via the CM command) can also be substituted for VMIN (in which case VMAX and VINC are ignored).


Maximum value of item range. VMAX defaults to VMIN for input values.

For result values, VMAX defaults to infinity if VMIN is positive, or to zero if VMIN is negative.


Value increment within range. Used only with integer ranges (such as for element and attribute numbers). Defaults to 1. VINC cannot be negative.


Absolute value key:



Check sign of value during selection.



Use absolute value during selection (sign ignored).

Command Default

All elements are selected.


Selects elements based on values of a labeled item and component. For example, to select a new set of elements based on element numbers 1 through 7, use ESEL,S,ELEM,,1,7. The subset is used when the ALL label is entered (or implied) on other commands, such as ELIST,ALL. Only data identified by element number are selected. Selected data are internally flagged; no actual removal of data from the database occurs. Different element subsets cannot be used for different load steps (SOLVE) in a /SOLU sequence. The subset used in the first load step is used for all subsequent load steps regardless of subsequent ESEL specifications.

This command is valid in any processor.

Elements crossing the named path (PATH) are selected. This option is available only in PREP7 and POST1. If no geometry data has been mapped to the path (via PMAP and PDEF, for example), the path assumes the default mapping option (PMAP,UNIFORM) to map the geometry prior to selecting the elements. If an invalid path name is given, the ESEL command is ignored (and the status of selected elements is unchanged). If no elements are crossing the path, the ESEL command returns zero elements selected.

For selections based on non-integer numbers (coordinates, results, etc.), items that are within the range VMIN -Toler and VMAX + Toler are selected. The default tolerance Toler is based on the relative values of VMIN and VMAX as follows:

  • If VMIN = VMAX, Toler = 0.005 x VMIN.

  • If VMIN = VMAX = 0.0, Toler = 1.0E-6.

  • If VMAXVMIN, Toler = 1.0E-8 x (VMAX - VMIN).

To override this default and specify Toler explicitly, issue the SELTOL command.

Valid Item and Component Labels ESEL, Type, Item, Comp, VMIN, VMAX, VINC, KABS
ELEM Element number.
ADJ Elements adjacent to element VMIN (VMAX and VINC fields are ignored). Only elements (of the same dimensionality) adjacent to lateral faces are considered. Progression continues until edge of model or until more than two elements are adjacent at a face.
CENTX, Y, ZX, Y, or Z location in the active coordinate system.
TYPE Element type number.
ENAME Element name (or identifying number).
MAT Material ID number.
REAL(blank)Real constant number.
 GCNGeneral contact/target elements (select all elements identified by real constant set number = 0). Remaining fields (VMIN, VMAX, etc.) are ignored.
ESYS Element coordinate system number.
PART LS-DYNA part number (applicable only to ANSYS LS-DYNA)
LIVE Active elements (EALIVE). VMIN and VMAX fields are ignored.
LAYER Layer number (where only composite elements with a nonzero thickness for the requested layer number are included) (LAYER).
SEC(blank)Cross section ID number (SECNUM)
 MATSelects the elements with the requested MAT ID specified via VMIN and VMAX as attached to the section.
STRA Straightened. See the description of the Item argument above.
SFEPRESElement pressure.
 CONVElement convection bulk temperature.
 HFLUXElement heat flux.
 FSIElement (acoustic) fluid-structure interaction flag.

 JSElement current density, magnitude only.
 MVDIElement magnetic virtual displacements flag.
 DGENElement diffusing substance generation rate.
 CHRGDElectric charge density.
PATHLabSelects all elements being crossed by the path with name Lab (PATH). If Lab = ALL, all elements related to all defined paths are selected.
Valid item and component labels for element result values are:
ETABLabAny user-defined element table label (ETABLE).
