Hi,
I get the following error when I used a 3-D mesh created using gmsh "The surface element (0, 65622) doesn't have an associated volume element" Can you tell me what this error means? I understand that the connectivity is a problem but don't know what to do. The mesh file format is OK. |

Try to create physical volume along with the physical surfaces.

Hi,
I have created physical surfaces and volumes withing gmsh by extrusion. I assume that's what you mean by physical volumes. Please correct me if I am wrong. Thanks!! Shashank |

You have to add a physical tags to the surfaces you want to add boundary conditions. The lateral surfaces of the extruded volume are not desirable in many cases. And also the extruded volume.
For example: num[] = Extrude {0,0,1} { Surface{1}; Layers{10}; };The variable "num" would contain the surface of the top of the extrusion as num[0], the floor of the extrusion as num[1], and the lateral surfaces of the extrusion as num[2,3...]. If you have more than one surface to extrude, the surfaces corresponding to the second extrusion are stored after the last lateral surface of the first extrusion in num[]. For example, if the first surface has 3 edges, the top of the second extrusion is in num[4]. I hope it can help you. |
