# Input files formats

In this page youâ€™ll find a brief explanaition of the format of each one of the files used by PRISSMA as an input.

An explanation of the words used to presents the formats are presented next:

- icell : id number of the cell
- nfaces : number of faces of this cell
- ncell : total number of cells in the domain
- nbfaces : total number of faces belonging to the boundary patch
- nnodes : total number of nodes in this cell
- ntcells : total number of cells in the mesh
- ntnodes : total number of nodes in the mesh
- ntfaces : total number of faces in the mesh
- [..] n times : expressions between brackets are repeated n times
- {..} n times : expression between brackets are writen in n different records

integer data is writen in blue

real data is writen in black
