cgrow

Mapdl.cgrow(action='', par1='', par2='', **kwargs)

Defines crack-growth information

APDL Command: CGROW

Parameters:

action

Specifies the action for defining or manipulating crack-growth data:

NEW

Initiate a new set of crack-growth simulation data (default).

CID

Specify the crack-calculation (CINT) ID for energy-release rates to be used in the fracture criterion calculation.

FCOPTION

Specify the fracture criterion for crack-growth/delamination.

CPATH

Specify the element component for crack growth.

DTIME

Specify the initial time step for crack growth.

DTMIN

Specify the minimum time step for crack growth.

DTMAX

Specify the maximum time step for crack growth.

FCRAT

Fracture criterion ratio (fc).

STOP

Stops the analysis when the specified maximum crack extension is reached.

METHOD

Define the method of crack propagation.

Notes

When Action = NEW, the Mapdl.cgrow() command initializes a crack-growth simulation set. Subsequent Mapdl.cgrow() commands define the parameters necessary for the simulation.

For multiple cracks, issue multiple Mapdl.cgrow("NEW") commands (and any subsequent Mapdl.cgrow() commands necessary to define the parameters) for each crack.

If the analysis is restarted (Mapdl.antype("","RESTART")), the Mapdl.cgrow() command must be re-issued.
