TABLE 1-24: VALID PROPERTY/VALUE PAIRS
PROPERTY NAME S L P PROPERTY VALUE DEFAULT DESCRIPTION
Surfmap ♦ color map Color map
Surfxdata ♦ string Surface x-axis expression
Surfydata ♦ string Surface y-axis expression
T ♦ ♦ ♦ vector Times for evaluation
U ♦ ♦ ♦ solution object or
vector
fem.sol or 0
Solution for evaluation
If the field fem.sol.u does not exist and the property U is not specified, expressions
not depending on the solution can still be plotted.
The notation colorspec in the value column denotes a color specification. See
postplot for a description of this.
The property Phase is described in posteval.
Examples
3D Example
clear fem
fem.geom = geomcsg({cylinder3});
fem.mesh = meshinit(fem);
fem.equ.c = 1; fem.equ.f = 1; fem.equ.da = 1;
fem.bnd.h = 1;
fem.shape = 2;
fem.xmesh = meshextend(fem);
fem.sol = femtime(fem,'tlist',0:0.01:0.1);
Plot solutions on a cross-section:
crosspts = [0 0 1;0 1 1;0 0 1];
postcrossplot(fem,2,crosspts,'surfdata','u','solnum',1:2:10,...
'crosslicecs','local')
Plot fourth solution on five cross-sections with geometry boundaries:
postcrossplot(fem,2,crosspts,'surfdata','u','solnum',4,...
'geom','on','refine',3,'axisequal','on',...
'spacing',5)
Plot on a boundary 6 for the last time value:
postcrossplot(fem,2,6,'surfdata','ux','cont','on','solnum',11)
Compare this with
postplot(fem,'tridata','ux','cont','on','bdl',6,'geom','on',...
'solnum',11)
Plot on a boundary 6 for some time values with overlaid mesh:
