The proposed meshfree GoFD approach can be extended to higher-dimensional problems by generalizing the construction of the transfer matrix from a given point cloud to a uniform grid in three or more dimensions. In higher dimensions, the point cloud would represent the discretization of the domain in a meshless manner, and the transfer matrix would be constructed using techniques suitable for the specific dimensionality. For example, in three dimensions, the Delaunay triangulation approach could be adapted to create tetrahedral elements for interpolation. The key would be to maintain the efficiency and accuracy of the method while handling the increased complexity of higher-dimensional geometries.
