I am using R2020b. While solving a PDE with myufunction for updating the boundary condition at each iteration, I keep getting the error message 'Unable to resolve the name results.NodalSolution'. Any help is welcome.

This was the code for the stl file

v = [x(:) y(:) z(:)];
V=v*1000;
faces=zeros(12,3);
faces(1,:)=[1, 2, 3];
faces(2,:)=[1, 3, 4];
faces(3,:)=[1, 2, 6];
faces(4,:)=[1, 6 ,5];
faces(5,:)=[2, 3, 7];

faces(7,:)=[3, 4, 8];
faces(8,:)=[3, 8, 7];
faces(9,:)=[4, 5, 8];
faces(10,:)=[4, 1, 5];
faces(11,:)=[5, 6 7];

TR=triangulation(T,v);

shp = alphaShape(x,y,z,a)
[faces, v] = boundaryFacets(shp);
fv.faces = faces;
fv.vertices = v;
trisurf(T,x,y,z);
stlwrite(TR,'tankdimension3d.stl')

You have a typo. It should be u=result.NodalSolution; not u=results.NodalSolution;
