New features in Version 4

 Grid Rotation

Under certain conditions it is preferable to discretize a domain using a rotated grid to minimize the number of grid blocks and thus to allow for a faster modeling cycle. Grids can be rotated using one of three commands.

Manual Grid Rotation

A grid can be manually rotated using the Rotate and Scale Dialog and by setting the grid angle.

Automatic Grid Rotation during Auto Grid Generation

When auto grid generation takes place Argus ONE can automatically calculate the grid angle that will minimize the number of grid blocks and thus also the number of inactive blocks.

In projects created by version 4 or later, automatic grid rotation is the default behavior.

Using automatic grid rotation

When this option is selected in the grid preferences the following dialog will appear when you click the magic wand above a domain contour to be grided.

The dialog allows you to decide whether you wish to use auto-rotation, and if not what, at which angle to rotate the grid.

GridAngle() Function

The GridAngle() function returns the grid angle of rotation. See description under new functions section in this supplement.
