numdesigns=5
nelx=30;
nely=30;
for i=1:numdesigns
volfrac=round((.3+(.8-.3)*rand(1,1)),1); %random # from .3 to .8
penal=3; %paper said "typically 3"
rmin=round((1.2+(1.5-1.2)*rand(1,1)),1); %filter size- range or?
%primary load is set to -1 (and applied at bottom right of beam)
%phantom load randomly changes magnitude + location
%added code lines 91+
phload=round((.1+(.3-.1)*rand(1,1)),2); %random magnitude from 0.1 to 0.3
phlocation=randi([round(2*(nelx+1)/3) nelx+1], 1,1); %from 2/3 beam to right end
toploadph(nelx,nely,volfrac,penal,rmin, phload, phlocation)
end
I get that both phload and phlocation are unrecognized. don't know why.
the beginning of the function looks like this:
function toploadph(nelx,nely,volfrac,penal,rmin, phload, phlocation);
Error says this:
Unrecognized function or variable 'phload'.
Error in toploadph>FE (line 94)
F(2*nelx*(phlocation-1)+ 2,2)=phload; %location represents vertical columns
Error in toploadph (line 16)
[U]=FE(nelx,nely,x,penal);
Error in generatetop99 (line 64)
toploadph(nelx,nely,volfrac,penal,rmin, phload, phlocation)

Make sure there is no any 'clear' command used. Check if unfortunately this varible get cleared by any way.

You are passing phload into toploadph, but toploadph is not passing it into FE which needs it.
We can also predict that FE is not a nested function within toploadph -- if it were nested, then it would have access to the parameters passed in to the nesting function.
