Running a case is described in the following page: http://www.code-saturne.org Two test cases are available, the former using an hexa-based grid and the latter a tetra-based grid. Test Case A deals with the flow in a bundle of tubes. A larger mesh (51M cells) is built from an original mesh of 13M cells. The original mesh_input file (already preprocessed for Code_Saturne) is to be found under MESH. The user subroutines are under XE6_INTERLAGOS/SRC The test case has been set up to run for 10 time-steps. Test Case B models a lid-driven cavity and the cells are all tetras. The total number of cells is about 110M. The mesh is called mesh_input and the usersubroutines are available under SRC_UEABS 10 time-steps are run.
