adpci

SpecialPurpose.adpci(action='', par1='', par2='', par3='', par4='', par5='', par6='', par7='', par8='', **kwargs)

Defines parameters associated with adaptive crack initiation.

Mechanical APDL Command: ADPCI

Parameters:

actionstr

Specifies action for defining or manipulating initial crack data:

• DEFINE - Command Specification for Action= DEFINE Initiate a new adaptive-crack calculation and assign an ID.

• GEOM - Command Specifications for Action= GEOM Define the geometry data for initializing a crack.

• DELE - Command Specifications for Action= DELE Delete the adpci data set associated with the specified ID.

• LIST - Command Specifications for Action= LIST List the adpci data set associated with the specified ID.

Notes

For adpci,GEOM,LCS, the ellipse center locates at the origin of the local coordinate system. The local coordinate system Y axis defines the plane normal of the ellipse, and X and Z axes define two orientations of the ellipse. (The LCS argument is equivalent to combining the CENTER and AXES arguments. Separate adpci,GEOM commands to specify those arguments are therefore not issued.)

Command Specifications

Command Specification for Action= DEFINE

• Par1 - adpci ID number.

• Par2 - Surface-node component name for defining the crack-initiation zone (must be 32 characters or less).

• Par3 - Material ID for defining the crack-initiation criterion.

• Par4 - Shape of the initialized crack:

  • ELLIPSE - Elliptical crack shape (default, and the only valid value).

Command Specifications for Action= GEOM

• Par1 - adpci ID number.

• Par2 - Crack geometry characteristic to define:

  • CENTER - Specify the ellipse center location.

  • AXES - Specify the directions of the two ellipse axes.

  • ALEN - Specify the lengths of two ellipse axes. This value is required when AXES or LCS is specified.

  • LCS - Local coordinate system number for defining the ellipse center location and axes directions. See adpci_notes below.

• Par3 - The first value to assign to the geometry characteristic specified via Par2 :

  • If Par2 = CENTER, the X coordinate of the ellipse center.

  • If Par2 = AXES, the X component of the first ellipse axis direction.

  • If Par2 = ALEN, the length of the first ellipse axis.

  • If Par2 = LCS, the local coordinate system number.

• Par4 - The second value to assign to the geometry characteristic specified via Par2 :

  • If Par2 = CENTER, the Y coordinate of the ellipse center.

  • If Par2 = AXES, the Y component of the first ellipse axis direction.

  • If Par2 = ALEN, the length of the second ellipse axis.

• Par5 - The third value to assign to the geometry characteristic specified via Par2 :

  • If Par2 = CENTER, the Z coordinate of the ellipse center.

  • If Par2 = AXES, the Z component of the first ellipse axis direction.

• Par6 - The fourth value to assign to the geometry characteristic specified via Par2 :

  • If Par2 = AXES, the X component of the second ellipse axis direction.

• Par7 - The fifth value to assign to the geometry characteristic specified via Par2 :

  • If Par2 = AXES, the Y component of the second ellipse axis direction.

• Par8 - The sixth value to assign to the geometry characteristic specified via Par2 :

  • If Par2 = AXES, the Z component of the second ellipse axis direction.

Command Specifications for Action= DELE

• Par1 - adpci ID (default = ALL).

Command Specifications for Action= LIST
