Plotting normal modes in Matlab

Plotting normal modes in Matlab

Plotting normal modes in Matlab

(OP)

Hi,

Could You help me with problem mentioned in the topic? I copied magnitude vector from eigenproblem results from Abaqus data [Link to data I used http://pastebin.com/mLCHKn6R (second column - don't know what to do with rest)]. I have problem in reproducing results in Matlab. I am trying to draw normal modes in Matlab, but I haven't got much luck so far.
Code I used in Matlab:
(s is data imported from aforementioned .txt file)

z=s(:,2);zz=reshape(z,11,13);
x= 0:10:120;y=0:10:100;[X,Y]=meshgrid(x,y);
y1=(0:1:100);x1=(0:1:120);
y1=y1';
zz2=interp2(X,Y,zz,x1,y1,'cubic');
[xx1,yy1]=meshgrid(x1,y1);
surf(xx1,yy1,zz2)

As You can see, the shape is completely different.



I would appreciate if you could help me what is wrong with my reasoning and show proper way to solve my problem.

All best regards,
Ian
