Hi,
I have a region ( variable 'nmask' in the .MAT file) on which I want to generate a Q4 mesh. In my current implementation, the nodes are not falling perfectly on the boundary of the region. Figure below should explain it further where red markers show the location of the nodes. Following code was used to generate these:
tx = mfc:subset:mlc;
ty = mfr:subset:mlr;
[TX,TY] = meshgrid(tx,ty);
nodeDetails = [(1:size(TX,1)*size(TX,2))', TY(:),TX(:)];
c = 0;
conect = zeros((size(TX,1)-1)*(size(TX,2)-1),4);
for j = 0:(size(TX,2)-2)
for i = 1: size(TX,1)-1
c = c + 1;
ii = j*(size(TX,1)) + i;
conect(c,:) = [ii, ii + 1, ii + size(TX,1) + 1, ii + size(TX,1)];
end
end
I am only interested in the white region. How can I also discard the other points?
