Combine two geometries by adding one inside a cell of another
creates nonempty cells inside
g3 = addCell(
g1 using all cells of
g2. All cells of the geometry
g2 must be
contained inside one cell of the geometry
g1. Ensure that the
geometries do not have enclosed cavities and do not intersect one another.
The combined geometry contains cells from both geometries. The cells from
g1 retain their original IDs, while the cells from
g2 are numbered starting with
N is the number of cells in
Added cells modify a geometry, but they do not modify the corresponding mesh. After
modifying a geometry, always call
generateMesh to ensure a proper
mesh association with the new geometry.
Combine Two Geometries
Create and plot a geometry.
g1 = multicuboid(2,2,2,"Zoffset",-1); pdegplot(g1,"CellLabels","on","FaceAlpha",0.5)
Import and plot another geometry.
g2 = importGeometry("DampingMounts.stl"); pdegplot(g2,"CellLabels","on","FaceAlpha",0.5)
Scale and move the second geometry to fit entirely within the cube
g2 = scale(g2,[1/1500 1/1500 1/100]); g2 = translate(g2,[-0.5 -0.5 -0.5]);
Plot the result.
Combine the geometries and plot the result. The combined geometry
g3 contains cells from both geometries. The cell from
g1 keeps its ID, and the cells from
g2 are now C2, C3, C4, and C5.
g3 = addCell(g1,g2); pdegplot(g3,"CellLabels","on","FaceAlpha",0.4)
g1 — 3-D geometry
