Hi all, I am using fluidity with a simple case of hexahedron element, unfortunately I got an error at the beginning of the program. I have tried the same case with tetrahedron element, it works fine. Could anyone tell me where is the fault? The error log, mesh file and fluidity options is post back, if you need any information please tell me. *** FLUIDITY ERROR *** Source location: (Element_Numbering.F90, 1369) Error message: Node is not part of an element in vertex_num. Backtrace will follow if it is available: Use addr2line -e

to decipher.
