MATLAB: PDE toolbox and load on nodes

load on nodesPartial Differential Equation Toolboxpde

I use the PDE Toolbox to analysis a discrete geometry, and I want to put the force vector on a point. But I can't define a point through the syntax "loadedVertex". Is there any other option to define the point? thank you!

The function addVertex was introduced in R2019b. You might be running an older version of the MATLAB to get this error.

MATLAB: It’s possible to update nodes value in a mesh that was created with pde toolbox

Hello Gabriel,

You can achieve this using geometryFromMesh function. Following your example:

results = solvepde(model);
u = results.NodalSolutions;
oldNodes = model.Mesh.Nodes;
newNodes = oldNodes + u';
elements = model.Mesh.Elements;
% Delete the geometry. As you will create new geometry with deformed mesh.
model.Geometry = []
newMesh = geometryFromMesh(model,newNodes,elements);

MATLAB: Export geometry out of model container

You can get this information easily in the latest version of MATLAB, which is R2018a. The function you need to use is findNodes.

Here is a simple example with block as geometry:

model = createpde;
gm = importGeometry(model,'Block.stl')
msh  = generateMesh(model);
vertexNodes = findNodes(msh,'region','Vertex',1:gm.NumVertices);
vertexCoordinates = msh.Nodes(:,vertexNodes)
