CylindricalGridDivision

Divide the mesh along a cylindrical grid. The innermost numbering of divisions is the radial bins, then comes the azimuthal bins, then the axial bins

The number of mesh divisions/regions is the product of the number of bins in each coordinate.

Points that lie outside the cylindrical grid may be assigned to the closest grid outer bins using the "assign_domain_outside_grid_to_border" parameter.

note

The "center" should be a point on the axis of the cylinder that also corresponds to the reference for the minimal ("cylinder_axial_min") and maximal ("cylinder_axial_max") axial extent of the cylinder.

Using a Positions object as the "center_positions" parameter, multiple cylindrical grids can be created around each position computed by that object. The division index of a point is then:

var element = document.getElementById("moose-equation-e30c092c-f27c-4e96-a447-ba6aa5c7a862");katex.render("\\text{division index} = (i - 1) N_{\\text{single division}} + \\text{division index in cylindrical grid centered around position i}", element, {displayMode:true,throwOnError:false});

with $var element = document.getElementById("moose-equation-bd18edac-3890-407b-89b7-06056d40f2ac");katex.render("i", element, {displayMode:false,throwOnError:false});$ the index in the Positions object of the position nearest from the point and $var element = document.getElementById("moose-equation-d99f226e-feff-4e8d-aaa2-7325edca02b3");katex.render("N_{\\text{single division}}", element, {displayMode:false,throwOnError:false});$ the number of divisions for a single cylindrical grid, based on the number of rings and axial discretization specified.

note

We have not implemented restrictions in the azimuthal direction so the entire ( $var element = document.getElementById("moose-equation-71cc0262-ad5c-4adb-9f11-000e558ad0b4");katex.render("0", element, {displayMode:false,throwOnError:false});$ , $var element = document.getElementById("moose-equation-056038ed-e3c1-49b4-9c84-92d8d3cd7668");katex.render("2 \\pi", element, {displayMode:false,throwOnError:false});$ ) arc will be split. This is a desirable extension of this object.

note

For points lying within the standard tolerance of an internal boundary of the cylindrical grid, this object will output a warning. If you do not mind the indetermination on which bins they belong to but do mind that a warning is output, please reach out to a MOOSE (or any MOOSE app) developer.
