MeshedRegion class

Namespace: Ans.DataProcessing

Summary

Describe a mesh.

Node and element scopings, element types, connectivity (list of node indices composing each element)

and node coordinates are the fundamental entities composing the meshed region.

Example

my_model = dpf.Model("../.../file.rst")

mesh = my_model.MeshedRegion

#access elements scoping

my_elements_scoping = mesh.ElementScoping

#access nodes scoping

my_nodes_scoping = mesh.NodeScoping

#get connectivity (ordered node ids) of one element

my_el_1 = mesh.ElementById(1)

my_el_1.NodeIds

#connectivity with only primary (corner) nodes

my_el_1.CornerNodeIds

#get coordinates

mesh.CoordinatesField #complete 3D field with scoping = mesh.NodesScoping

#or node by node

my_node_1 = mesh.NodeById(1)

my_node_1.X

my_node_1.Y

my_node_1.Z



#create meshed region

mesh = dpf.MeshedRegion(4, 1)

mesh.AddNode(1, [ 0.0, 0.0, 0.0 ])

mesh.AddNode(2, [ 1.0, 0.0, 0.0 ])

mesh.AddNode(3, [ 1.0, 1.0, 0.0 ])

mesh.AddNode(4, [ 0.0, 1.0, 0.0 ])

mesh.AddShellElement(1, [ 0, 1, 2, 3 ])
