matlap featool grid error

I want to use 'Refine' in grid but i can't because this error : [featool geom_decompose : wrong edge numbering]

How do i have to?

This was probably due to a bug. It should have been fixed in the latest release. Either update your version, or decrease the grid size and remesh.

Hi,

After reading your question, I understand that you want to know about the implementation of the refine function.

The error message you are encountering, "[featool geom_decomposed : wrong edge numbering]," might be due to the problem with the edge numbering in a geometric decomposition in the FEATool (Finite Element Analysis Toolbox) for MATLAB.

To resolve this issue, you can try the following steps:

1. Check the input geometry to make sure that it is properly defined and that all edges are correctly connected to the vertices.
2. Make sure the edge numbering is consistent and correct.
3. If the error persists, try to simplify the geometry by removing unnecessary details and retry the refine function.

Also, you can use interp2 function, whose documentation can be found from below mentioned link:

• https://www.mathworks.com/help/matlab/ref/interp2.html?searchHighlight=interp2&s_tid=srchtitle_interp2_1

The below mentioned example can help you to better understand the interp2 function:

[X,Y] = meshgrid(-3:3);
V = peaks(X,Y);
figure
surf(X,Y,V)

[Xq,Yq] = meshgrid(-3:0.25:3);
Vq = interp2(X,Y,V,Xq,Yq);
figure
surf(Xq,Yq,Vq);
