how to give value stress from excel give color in my mesh

Answer 1

You can coonsider using this package: https://in.mathworks.com/matlabcentral/fileexchange/32719-postprocessing-in-fem

[KSSV]

You have to procced somehtink like shown.

coor = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1041210/coordinat.xlsx') ;
nodes = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1041215/nodes.xlsx') ;
T = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1041220/valuestressinelement.xlsx') ;
p = table2array(coor) ; 
z = table2array(T) ;

x = p(:,1) ; y = p(:,2) ; 

nx = length(unique(x)) ;
ny = length(unique(y)) ;
X = reshape(x,nx,ny) ; 
Y = reshape(y,nx,ny) ; 
Z = reshape(z,nx-1,ny-1) ; 
imagesc(x,y,Z)

this not answer sir,

I want the results of the ansys data to be similar in matlab. from the stress data I got, I was confused about how to get the data into the elements that had been made according to the specified color range.

[Nobeth Bastanta Ginting]

hai sir can you teach me from platform zoom or other platform? thanks if you want because my project is stuck.

[KSSV]

There is problem with your data.Coordinates and nodes are same.

[Nobeth Bastanta Ginting]

i am sorry sir this my data nodes

[KSSV]

The present attached nodes data is correct. You can follow the package which I have shown first. But note that, the strees values which you have given, these values are at the mid points of the elements. You need to extract, the stress values at each node. At present stress data is 100x1. If this is the case, then the answer which I have shown will work. If you extract stress values at every node, then this will be of size 121x1; this case use the package which I have given link.

hi sir i get my want. but how to get element 10x10? because i see element not 10x10. and how to change axis to range 0-100 in x and y. thank you sir

[Nobeth Bastanta Ginting]

value stress in middle of element sir so i want value stress in element not in nodes because my teacher say stress in element not in nodes

Not sure what you want to do exactly but it seems this is an application of mesh function.

As you can see (click the link), you can specify the color with the fourth argument (CO) of the function:

[X,Y,Z] = peaks(25);
CO(:,:,1) = zeros(25); % red
CO(:,:,2) = ones(25).*linspace(0.5,0.6,25); % green
CO(:,:,3) = ones(25).*linspace(0,1,25); % blue
mesh(X,Y,Z,CO)

[Nobeth Bastanta Ginting]

the plot is not like that sir. the result is plane stress 2D
