swgen

Mapdl.swgen(ecomp='', swrd='', ncm1='', ncm2='', snd1='', snd2='', shrd='', dirx='', diry='', dirz='', itty='', icty='', **kwargs)

Creates a new spot weld set.

APDL Command: SWGEN

Parameters
  • ecomp – Name to identify the new spot weld. This name will be used for the element component containing the new contact, target, and beam elements generated for the spot weld set.

  • swrd – Spot weld radius.

  • ncm1 – Name of a component containing nodes on the first spot weld surface, or a meshed area number for the surface.

  • ncm2 – Name of a component containing nodes on the second spot weld surface, or a meshed area number for the surface.

  • snd1 – Node number of the first spot weld node corresponding to the first surface (NCM1). This node can be on or close to the first surface.

  • snd2 – Node number of the second spot weld node corresponding to the second surface (NCM2). This node can be on or close to the second surface. ANSYS will create the node if it is not specified.

  • shrd – Search radius. Defaults to 4 times the spot weld radius SWRD.

  • dirx – Spot weld projection direction in terms of normal X, Y, and Z components.

  • diry – Spot weld projection direction in terms of normal X, Y, and Z components.

  • dirz – Spot weld projection direction in terms of normal X, Y, and Z components.

  • itty – Target element type ID.

  • icty – Contact element type ID.

Notes

This command creates a new spot weld set. You can add more surfaces to the set using SWADD after the initial SWGEN command. However, the maximum number of allowable surfaces (including the 2 surfaces used for the original set) for each spot weld set is 11.

Ecomp, SWRD, NCM1, NCM2, and SND1 must be specified. SND2, SHRD, DIRX, DIRY, DIRZ, ITTY, ICTY are optional inputs. If the second spot weld node (SND2) is specified, that node is used to determine the spot weld projection direction, andDIRX, DIRY and DIRZ are ignored.

If ITTY is specified, the following corresponding target element key option must be set: KEYOPT(5) = 4. If ICTY is specified, the following corresponding contact element key options must be set: KEYOPT(2) = 2, KEYOPT(12) = 5.

Use the SWLIST and SWDEL commands to list or delete spot welds. See Creating a Basic Spot Weld Set with SWGEN for detailed information on defining spot welds.
