how to plot deformation with value from ansys to matlab

in ansys

data displacements =

UX = displacements (:,2);

UY = displacements (:,3);

data coordinates = coordinates(:,2:end);

data nodes = nodes(:,2:end);

i want value deformation in nodes. can you help me? and can get like in ansys. Thank you.

you can use the patch command, see the method below

coordinates = readmatrix("coordinates.csv");
displacements = readmatrix("displacements.csv");
nodes = readmatrix("nodes.csv");

scale = 5e8; % scale the very small deformations (otherwise you won't see anything)

figure
subplot(1,2,1)
patch('Faces',nodes(:,2:end),'Vertices',coordinates(:,2:end),'FaceAlpha',0.3)
view(3)
axis equal
title("Undeformed")
view([150 45])

subplot(1,2,2)
patch('Faces',nodes(:,2:end),'Vertices',coordinates(:,2:end) + displacements(:,2:end).*scale,'FaceVertexCData', sqrt( sum(displacements(:,2:end).^2,2)),'FaceColor','interp')
view(3)
axis equal
colormap jet
title("Deformed")
view([150 45])

clear

clc

load coordinates.dat ;

coordinates = coordinates(:,2:end);

load nodes.dat;

nodes = nodes(:,2:end);

load displacements.dat ;

scale = 5e8; % scale the very small deformations (otherwise you won't see anything)

figure

subplot(1,2,1)

patch('Faces',nodes,'Vertices',coordinates,'FaceAlpha',0.3)

view(3)

axis equal

title("Undeformed")

view([150 45])

subplot(1,2,2)

patch('Faces',nodes,'Vertices',coordinates + displacements.*scale,'FaceVertexCData', sqrt( sum(displacements.^2,2)),'FaceColor','interp')

view(3)

axis equal

colormap jet

title("Deformed")

view([150 45])

my question : hello sir i use your coding but i make with use file .dat but the value is same. why in deformation no out the no deformation results. because in line 17 it havent problem. can you help me ?

You haven't defined the variation "displacements" which will be used in the patch of subplot(1,2,2).
