multiphysics
Purpose
multiphysics
Multiphysics function.
Syntax
Description
fem1 = multiphysics(fem,...)
xfem1 = multiphysics(xfem,...)
fem1 = multiphysics(fem) combines the applications in fem.appl to the
composite system fem1.
xfem1 = multiphysics(xfem), where xfem is a structure with a field fem,
performs the above call for all of the structures xfem.fem{:}. The results are placed
in xfem1.fem. In addition the fields elemmph and eleminitmph created for each
structure in xfem.fem are concatenated and placed as fields in xfem1.
The function multiphysics accepts the following property/values:

PROPERTY VALUE DEFAULT DESCRIPTION
Bdl
Cell array of, or just
an Integer vector or
NaN
all boundaries
Only affect the indicated
boundaries in fem.bnd
Defaults on | off off Return default fields

Outsshape
Pdl
Cell array of, or just
a cell with ga, f, r,
or g, or the strings
off or on
Cell array of, or just
an integer vector or
NaN
Cell array of, or just
an coefficient |
general | weak
Cell Array of, or just
an integer or a NaN
Cell array of, or just
an integer vector or
a NaN
on (for general
form)
all edges
The most
general form of
the subsystems
generated from
appl’s
all points
Differentiate these
coefficients
As Sdl but for fem.edg.
Output form
Output sshape.
NaN is the same as not
providing Outsshape.
Can also be given for each
structure in xfem.fem, by
giving a cell array of
values.
As Sdl but for fem.pnt.
