- op_numnumber of order parameters to create
C++ Type:unsigned int
Controllable:No
Description:number of order parameters to create
- random_typeThe type of random polycrystal initial condition. Whether one order parameter is chosen to be 1 at each node or if each other parameter continuously varies from 0 to 1
C++ Type:MooseEnum
Controllable:No
Description:The type of random polycrystal initial condition. Whether one order parameter is chosen to be 1 at each node or if each other parameter continuously varies from 0 to 1
- var_name_basespecifies the base name of the variables
C++ Type:std::string
Controllable:No
Description:specifies the base name of the variables
PolycrystalRandomICAction
Overview
This action creates the initial conditions (ICs) for the op_num
order parameters used to represent a polycrystal with a random initial condition.
The action creates the IC for each of the variables with PolycrystalRandomIC.
Example Input File Syntax
The PolycrystalRandomICAction
is accessed through the ICs/PolycrystalICs
block, as shown below.
[GlobalParams]
# Parameters used by several kernels that are defined globally to simplify input file
op_num = 10 # Number of grains
var_name_base = gr # Base name of grains
