SpiralAnularMeshGenerator

Overview

This MeshGenerator object allows the user to create an annular mesh. The nodes are located on several concentric rings, and the elements are of type Tri3 (they can be Tri6 if the user changes the value of the use_tri6 parameter to true).

The user can choose the inner and outer radii, the number of rings, and finally the number of nodes on each ring. Given all these parameters, the radial bias will be computed automatically.

Input Parameters

inner_radiusThe size of the inner circle.
C++ Type:double
Options:
Description:The size of the inner circle.
nodes_per_ringNumber of nodes on each ring.
C++ Type:unsigned int
Options:
Description:Number of nodes on each ring.
num_ringsThe number of rings.
C++ Type:unsigned int
Options:
Description:The number of rings.
outer_radiusThe size of the outer circle. Logically, it has to be greater than inner_radius
C++ Type:double
Options:
Description:The size of the outer circle. Logically, it has to be greater than inner_radius

Required Parameters

cylinder_bid1The boundary id to use for the cylinder (inner circle)
Default:1
C++ Type:short
Options:
Description:The boundary id to use for the cylinder (inner circle)
exterior_bid2The boundary id to use for the exterior (outer circle)
Default:2
C++ Type:short
Options:
Description:The boundary id to use for the exterior (outer circle)
initial_delta_rWidth of the initial layer of elements around the cylinder.This number should be approximately 2 * pi * inner_radius / nodes_per_ring to ensure that the initial layer of elements is almost equilateral
C++ Type:double
Options:
Description:Width of the initial layer of elements around the cylinder.This number should be approximately 2 * pi * inner_radius / nodes_per_ring to ensure that the initial layer of elements is almost equilateral
use_tri6FalseGenerate mesh of TRI6 elements instead of TRI3 elements.
Default:False
C++ Type:bool
Options:
Description:Generate mesh of TRI6 elements instead of TRI3 elements.

Optional Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector
Options:
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Options:
Description:Set the enabled status of the MooseObject.
