# File and Data Format/Reading Data From Files

AcuSolve input file supports two mechanisms for entering list and array data.

The The data may be entered directly into the input file, such as in the following example:
COORDINATE {
coordinates =  {1, 1.00, 1.25, 1.50;
2, 1.10, 1.30, 1.55;
3, 1.15, 1.35, 1.60;
4, 1.25, 1.40, 1.65;
}
}

Or, the data may be read from an external file.

An external file can be referenced in the input file through the Read command. The path of the file can be absolute or relative to the location of the problem directory. For example, if the file is in the same directory as the input file:
COORDINATE {
}
If the file is stored inside MESH.DIR directory:
COORDINATE {
}
