how to plot deformation with value from ansys to matlab

15 views (last 30 days)
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

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 ?
