The node has a ring of nodes on Surface A and a ring of nodes on surface B. If this is not what you intended, then it alerts you to the problem so you can fix it. However, this won't hurt the solver and may be fine, if it is what you intended. Best regards, Simon ...
as COMSOL's "id" numbering is not on the elements but on the higher level entities (most other FEM tools I know about uses the elements as entities). If a node belongs to a higher level domain boundary it inherits the boundary properties. So in union mode a boundary of a 3D domain...
A non-manifold node is a node with more than one ring of nodes around it. This can happen when you pinch two surfaces together. At the point where they touch, there is a ring of nodes on each of the surfaces that touch at that point. Other interesting combinations are also possible. ...
The fundamental feature of this process is the definition of an area, called influence zone , which controls the node insertion and thus avoids edge intersection tests. Further, the generated mesh is refined through an extension of the Laplacian smoothing . It allows an optimization of the ...
To demonstrate the robustness of the node pruning algorithm we render a number of complex implicit surfaces such as high order polynomial surfaces and Gaussian curvature surfaces. We also compare the algorithm with ray casting interms of speed and image quality. For the surfaces presented here, ...

The construction method is feature-based - every reference model has pre-defined features, and the feature template of the constructed object is related to the features of the reference model by feature node encoding. Therefore, the surfaces derived from one reference model can be regenerated ...
This is done by first generating nodes on the boundaries, and then by generating nodes inside boundaries.; Delaunay Triangulation with incremental node insertion method has been primarily used since it allows constrained nodes to be used in every stage of the mesh generation process. The method ...
A few existing works have considered the node attributes plays a crucial role in the quality of network embedding. They use the non-negative matrix factorization (NMF) method to mine the network information of network structure and node attributes respectively. Considering the reconstruction error of...
