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
, theMapdl.cgrow()
command initializes a crack-growth simulation set. SubsequentMapdl.cgrow()
commands define the parameters necessary for the simulation.For multiple cracks, issue multiple
Mapdl.cgrow("NEW")
commands (and any subsequentMapdl.cgrow()
commands necessary to define the parameters) for each crack.If the analysis is restarted (
Mapdl.antype("","RESTART")
), theMapdl.cgrow()
command must be re-issued.For additional details on this command, see https://www.mm.bme.hu/~gyebro/files/ans_help_v182/ans_cmd/Hlp_C_CGROW.html
