The PHAST Grid Options dialog box is used to change certain options related to the grid in PHAST. To display the dialog box, select Model|PHAST Grid Options...
If the model is logically a one- or two-dimensional model, the user can use the Chemistry dimensions checkboxes to choose which dimensions should be used for the chemistry calculations.
If the model is a vertical cross sectional model, the user may wish to have the output from the model printed in the “*.o” output file in XZ orientation rather than the default XY orientation. The user can make that selection in the PHAST Grid Options dialog box.
