Hi, I am trying to create a reservoir model with unstructured grids. The reservoir is box shaped, with two horizontal wells on one side, and one vertical well on the other side. The model is basically a box with three cylinders inside.
Initially I succeeded in creating the 3D mesh. However, later I found that the mesh from the cylinder and the box were different and intersecting with each other. Based on the information from the web, I need to embed the surfaces inside the volume. After successfully embedding the surfaces, the 2D mesh looks good. There are no longer intersecting grids However, when I try to run the 3D mesh, it fails. I get the following error message: Info : Done meshing 2D (0.715054 s) Info : Meshing 3D... Info : Delaunay Meshing 4 volumes with 4 connected components Info : Meshing volume 227 (Delaunay) Info : 7174 points 36783 edges and 14324 faces in the initial mesh *Info : Found void regionInfo : Found void regionInfo : Found void regionInfo : Found void regionError : No tetrahedra in region 227 0* *Info : 3D point insertion terminated (7204 points created):* Info : - 0 Delaunay cavities modified for star shapeness Info : - 0 points could not be inserted Info : - 0 tetrahedra created in 0.010615 sec.
