elepspec
Examples
Given a single-geometry fem structure with an xmesh field, extract elements and
add an additional pattern that can be used by other elements and update the xmesh.
elstr = fem.xmesh.getElements;
clear elem;
for i=1:length(elstr)
elem{i} = eval(elstr(i));
if strcmp(elem{i}.elem,'elepspec')
iepspec = i;
end
end
elstr = fem.xmesh.getInitElements;
clear eleminit;
for i=1:length(elstr)
eleminit{i} = eval(elstr(i));
end
newptrn = length(elem{iepspec}.geom{1}.ep)+1;
elem{iepspec}.geom{1}.ep{newptrn} = {'s(1)' {{'0.5'}}};
fem.elem = elem;
fem.eleminit = eleminit;
Here, additional elements using the constraint pattern with index newptrn can be
added to the fem.elem field.
fem.xmesh = meshextend(fem,'standard','off');
