# iRIC grid CSV file (*.csv)¶

The iRIC grid CSV file (*.csv) is a text file that stores grid shapes and grid attributes of single-block BFC grid.

In columns with header X, Y, and Z grid node coordinates are stored. In the following columnd, grid attributes values are stored. In the header row, Grid attribute names are stored with prefix “N_” (in case of attribute defined at nodes) or “C_” (in case of attribute defined at cells).

For attributes defined at cells, value 0 is stored at rows for I = IMax and J = Jmax, as dummy data.

List 16 shows an example of iRIC grid CSV file.
