geomanalyze
Purpose
geomanalyze
Decompose and analyze geometry of FEM problem.
Syntax fem = geomanalyze(fem, ...)
fem = geomanalyze(fem, draw, ...)
[fem, map] = geomanalyze(fem, ...)
Description
fem = geomanalyze(fem,...) analyzes and updates the geometry data for the
model defined by fem.
fem = geomanalyze(fem, draw, ...) analyzes and updates the geometry data
in the model defined by fem. draw is one or several input arguments given in the
same ways as in geomcsg.
[fem, map] = geomanalyze(fem, ...) additionally returns a cell array of vectors
representing the mappings for the different domains. Each element in these vectors
gives the associated index of that entity in fem.geom before the call.
The function supports the following property/values:
TABLE 1-53: VALID PROPERTY/VALUE PAIRS
PROPERTY
NAME
PROPERTY VALUE DEFAULT DESCRIPTION
Geomnum integer 1 Geometry number
Imprint on | off on Make imprints when creating
pairs
Ns cell array of strings {} Name space
Paircand
all | none | cell
array of strings
not
specified
Specifies the geometries
among which pairs are created
Repairtol positive scalar 0.0 Tolerance for repairing gaps
Sf string union Boolean expression
Solidify on | off off Coerce the result to a solid
If the property paircand is not specified, the geometry data in the model is the
result of the boolean operation specified in the property sf. See geomcsg for more
details.
If the property paircand is specified, an assembly geometry is created. In addition
identity pairs are created using the property imprint. See geomgroup for details.
The above properties are explained in geomcsg and geomgroup respectively.
Example
The following is an example of a circle containing the source for the model, moving
through two different subdomains.
