The unstructured mesh based geometry is a by-product of the unstructured mesh-based multi-physics interface. It can be used to create a geometry universe based on an unstructured mesh.

Input Syntax

The unstructured mesh based geometry can be created by using the solid 1 or solid 3 input card.

Geometry only (solid 1)

solid 1 UNI BGUNI
MESH_SPLIT MESH_DIM SZ1 SZ2 ... SZMESH_DIM
POINTS_FILE
FACES_FILE
OWNER_FILE
NEIGHBOUR_FILE
MATERIALS_FILE

The first solid type creates an unstructured mesh-based geometry universe. Input values are:

UNI  : universe name for the irregular geometry
BGUNI  : name of the background universe filling all undefined space
MESH_SPLIT  : Splitting criterion for the adaptive search mesh (maximum number of geometry cells in search mesh cell)
MESH_DIM  : number of levels in the adaptive search mesh
SZi  : Size of the search mesh at level i
POINTS_FILE  : Path to the unstructured mesh points file
FACES_FILE  : Path to the unstructured mesh faces file
OWNER_FILE  : Path to the unstructured mesh owner file
NEIGHBOUR_FILE  : Path to the unstructured mesh neighbour file
MATERIALS_FILE  : Path to the unstructured mesh materials file

Geometry and multi-physics data (solid 3)

solid 3 UNI BGUNI
INTERFACE_FILE

It is also possible to create the geometry and bring in temperature and/or density data on the same mesh. In this case, most of the parameters are given in a separate multi-physics interface file which can be re-read by Serpent to update the fields between coupled calculation iterations. The input values in the main input file are:

UNI  : universe name for the irregular geometry
BGUNI  : name of the background universe filling all undefined space
POINTS_FILE  : Path to the interface file containing the rest of the parameters


The input format of each of the linked files is based on the OpenFOAM file format.
