Hello,
As per my understanding, to visualize the temperature distribution in a section (slice) of an irregular 3D shape can be achieved using the "slice" function. This is useful for examining the internal temperature distribution at a particular plane within the domain.
Given the coordinates of the nodes and the temperature at each node please refer to the following steps below to a possible workaround to the problem:
- Create a 3D grid that covers the domain of the model to capture the details of the temperature distribution.
- Use "griddata" function to interpolate the temperature data from the irregular mesh onto the 3D grid.
- Display the temperature disribution on the slice through the 3D grid using "slice" function.
As you are working with transient results and want to visualize the temperature at a specific time step, please extract the temperature data "u" for that time step before performing the interpolation.
Please refer to the code below for reference.
% Assuming x, y, z, and u contain the node coordinates and temperature
F = scatteredInterpolant(x, y, z, u); % Create an interpolant function
% Define the limits and resolution of the grid
xlin = linspace(min(x), max(x), 100);
ylin = linspace(min(y), max(y), 100);
zlin = linspace(min(z), max(z), 100);
% Create the grid
[X, Y, Z] = meshgrid(xlin, ylin, zlin);
% Interpolate the temperature onto the grid
U = F(X, Y, Z);
% Choose the slice positions (modify as needed)
xslice = []; % Empty means no slice along X
yslice = []; % Empty means no slice along Y
zslice = mean(z); % Slice in the middle of the Z domain
% Create the slice plot
slice(X, Y, Z, U, xslice, yslice, zslice)
shading interp % Optional for smoother color transition
colorbar % To show the temperature scale
xlabel('X')
ylabel('Y')
zlabel('Z')
