Lua: Create Meshes with create_mesh

Description

In Lua context, modalys.create_mesh creates a mesh from a parameter table. The same function is also available as create_mesh, make_mesh, and modalys.make_mesh.

Lua Syntax

local mesh = modalys.create_mesh{
    kind = "single-point",
    position = { 0, 0, 0 }
}

Supported Kinds

The implementation currently handles the following values for kind:

• read-from-file or from-file
• single-point
• add
• copy
• edge
• quadrilateral
• restrict-quadrilateral
• restrict-plane
• restrict-line
• restrict-point or restrict-points

The hexahedra, beam, and restrict-edge kinds are present as placeholders in the Lua implementation.

Examples

local point = create_mesh{
    kind = "single-point",
    position = { 0, 0.1, 0 }
}

local edge = create_mesh{
    kind = "edge",
    position1 = { 0, 0, 0 },
    position2 = { 1, 0, 0 }
}

local quad = create_mesh{
    kind = "quadrilateral",
    vertices = {
        { 0, 0, 0 },
        { 1, 0, 0 },
        { 1, 1, 0 },
        { 0, 1, 0 }
    }
}

local combined = create_mesh{
    kind = "add",
    parts = { edge, quad }
}

Reading a Mesh File

local mesh = create_mesh{
    kind = "read-from-file",
    path = "diapason.mesh",
    scale = 1
}
