Discrete 2-D or 3-D geometry description
DiscreteGeometry describes a 2-D or 3-D geometry in the
form of a discrete geometry object.
ThermalModel objects have a
Geometry property, which can be an
Create a discrete geometry for your model by using one of the following approaches:
importGeometry to import a 2-D
or 3-D geometry from an STL file and attach it to the model.
geometryFromMesh to reconstruct a
2-D or 3-D geometry from mesh and attach it to the model.
multisphere to create a 3-D
geometry. Then assign the resulting geometry to the
Geometry property of the model. For example, create a
PDE model and add the following geometry formed by three spheres to the
model = createpde; gm = multisphere([1,2,3]); model.Geometry = gm;
extrude to create a 3-D geometry by vertically extruding a
