WebReconstruct a geometry from a mesh by using geometryFromMesh . This function works with triangulated meshes, including planar, volume, and surface triangulation that bounds a closed volume. Create a geometry: Stack or nest cubes, cylinders, or spheres to create a geometry for a 3-D problem. Extrude a 2-D geometry into a 3-D geometry. WebMay 22, 2024 · The MATLAB contours function creates coordinate data that (when the shape is closed) has a coordinate point that starts and ends on the same point. The decsg function, however, only asks for the coordinate point at the beginning point of the edge for a polygon, this was causing problems when run iteratively - but was fine when run for one …

WebJan 16, 2024 · Accepted Answer: Alan Weiss. Dear Matlab community, I wish to perform 3D thermal simulation using the pde toolbox (which works amazingly by the way). I work with a open source software to make my STL file. I wish to solve my pde on an inhomogeneous system. For instance two domains with different thermal conductivities. WebMar 18, 2024 · This is possible, just not by meshing using the tools inside of MATLAB. You can use functions like geometryfrommesh to import a mesh made outside of MATLAB. Using tools like GMSH or Tetgen will give you complete control over your meshing parameters and optimisaton.

Multidomain Geometry Reconstructed from Mesh

WebJun 4, 2024 · Hi, I am trying to use the geometryFromMesh to import the geometry and mesh created by delaunayn in matlab. I have checked for coplanarity and other "bugs" and everything seems fine. There are some positive nodes and some negative nodes in the mesh. For those nodes that have negative values, the volume can be negative.

The first part of the example generates a mesh and divides the mesh elements into two groups. The second part of the example creates a two-domain geometry based on this division.

WebApr 28, 2024 · I found an explanation saying that Matlab versions after 2024b, no longer support import STL's with "multidomain geometries". If true, this feels extremely limiting on the part of Mathworks. In addition, I have found some people suggesting to use "stlread()", then use the resulting triangulation to create a geometry using "geometryFromMesh()". WebFeb 27, 2024 · pdeModeler is for 2-D problems, so I assume that you have 2-D geometry. In this case, you can use a parametrized function for 2-D geometry creation. You can also use CSG modeling in the pdeModeler app, using an ellipse as one element. Alan Weiss. MATLAB mathematical toolbox documentation.
