sfe

Mapdl.sfe(elem='', lkey='', lab='', kval='', val1='', val2='', val3='', val4='', **kwargs)

Specifies surface loads on elements.

APDL Command: SFE

Parameters
  • elem – Element to which surface load applies. If ALL, apply load to all selected elements [ESEL]. If Elem = P, graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). A component name may be substituted for Elem.

  • lkey – Load key or face number associated with surface load (defaults to 1). Load keys (1,2,3, etc.) are listed under “Surface Loads” in the input data table for each element type in the Element Reference.

  • lab – Valid surface load label. Load labels are listed under “Surface Loads” in the input table for each element type in the Element Reference.

  • kval

    Value key. If Lab = PRES:

    0 or 1 - VAL1 through VAL4 are used as real components of pressures.

    2 - VAL1 through VAL4 are used as imaginary components of pressures.

  • val1 – First surface load value (typically at the first node of the face) or the name of a table for specifying tabular boundary conditions. Face nodes are listed in the order given for “Surface Loads” in the input data table for each element type in the Element Reference. For example, for SOLID185, the item 1-JILK associates LKEY = 1 (face 1) with nodes J, I, L, and K. Surface load value VAL1 then applies to node J of face 1. To specify a table, enclose the table name in percent signs (%), e.g., %tabname%. Use the *DIM command to define a table. Only one table can be specified, and it must be specified in the VAL1 position; tables specified in the VAL2, VAL3, or VAL4 positions will be ignored. VAL2 applies to node I, etc.
