\page use_existing_page Use Edges/Faces to be Created Manually
The algorithms Use Edges to be Created Manually and
Use Faces to be Created Manually allow creating a 1D or a 2D mesh
in a python script (using AddNode, AddEdge
and AddFace commands) and then using such sub-meshes in the
construction of a 2D or a 3D mesh.
For example, you want to use standard algorithms to generate 1D and 3D
meshes and to create 2D mesh by your python code. For this, you
- create a mesh object, assign a 1D algorithm,
- invoke \b Compute command, which computes a 1D mesh,
- assign Use Faces to be Created Manually and a 3D algorithm,
- run your python code, which creates a 2D mesh,
- invoke \b Compute command, which computes a 3D mesh.
\warning Use Edges to be Created Manually and Use Faces to
be Created Manually algorithms should be assigned _before_
mesh generation by the Python code.
Consider trying a sample script demonstrating the usage of
\ref tui_use_existing_faces "Use Faces to be Created Manually"
algorithm for construction of a 2D mesh using Python commands.
