The first block in the gridfile, the geometry information block defines the dimensions of the flow domain.
Syntax
BEGIN DOMAIN
DOMAIN_TYPE( TWODIMENSIONAL | AXISYMMETRIC | THREEDIMENSIONAL )
END
For example, the syntax for a three-dimensional flow geometry is:
BEGIN DOMAIN
THREEDIMENSIONAL
END
Comments
The string DOMAIN_TYPE must be replaced with one of the three valid entries, TWODIMENSIONAL, AXISYMMETRIC, and THREEDIMENSIONAL. The default value is THREEDIMENSIONAL.
For 2D and axisymmetric models, the model must lie in the X-Y plane. For axisymmetric models, the X-axis is assumed to be the axis of symmetry.
