it's possible to update nodes value in a mesh that was created with pde toolbox?

Hello,

i'm trying to update my mesh nodes values with the result of a simulation. What i like to do is something like this:

results = solvepde(model);
u = results.NodalSolutions;
mesh.Nodes = mesh.Nodes + u;

i know that this last line is wrong, but exist a function that do this?

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);

Thank you Ravi, i will try this later.... But, geometryFromMesh creates new points and elements,

other than the ones I've been through, right?

Hi Gabriel,

Use the two LHS arguments to retain the same mesh as defined by newNodes and elements.

[geom, msh] = geometryFromMesh(model,newNodes,elements);
