hello
try this
the text file used for my code is attached
hope it helps
filename = 'text.txt';
D=readlines(filename); % read as string array
%% 1/ get *Mesh Parameters*
tmp = split(D(contains(D,'Elements average length')),':');
Elements_average_length = str2num(tmp(2));
tmp = split(D(contains(D,'Fibres direction elemements factor')),':');
Fibres_direction_elemements_factor = str2num(tmp(2));
%% 2/ get data
% first block of 4 lines
idx = find(contains(D,'Delta:'))
L4 = D(idx:idx+3);
% blocks of ID data (labels, values)
idx = find(contains(D,'ID:'))
Ldata = D(idx(1):idx(end)+2);
% export to text file
out = [L4;Ldata];
writematrix(out,'out.txt');
% for information / use ?
for ci =1:numel(idx)
labels{ci} = split(D(idx+1));
values{ci} = str2double(split(D(idx+2)));
end
