The procedure for performing isovalue adaption is as follows:
Region Adaption panel, choose the
If you choose
Inside, cells with centroids within the specified region will be marked or refined.
If you choose
Outside, cells with centroids outside the specified region will be marked or refined.
Specify the shape of the region.
In 2D, you may choose a
Cylinder. In 3D, you may choose a
Define the region by entering values into the panel or by using the mouse.
In the panel the inputs are as follows:
To define a hexahedron or quadrilateral, enter the coordinates of two points defining the diagonal of the box.
For a hexahedron, define (
Xminimum,Yminimum,Zminimum) and (
Xmaximum,Ymaximum, Zmaximum). For a quadrilateral, define (
Xminimum,Yminimum) and (
To define a sphere or circle, enter the values for the
Radius and the coordinates of its center; (
Xcenter, Ycenter, Zcenter) for a sphere or (
Xcenter, Ycenter) for a circle.
To define a cylinder, enter the value for the
Radius and the minimum and maximum coordinates defining the cylinder axis; (
X-Axis Min, Y-Axis Min, Z-Axis Min) and (
X-Axis Max, Y-Axis Max, Z-Axis Max) for 3D or (
X-Axis Min,Y-Axis Min) and (
X-Axis Max,Y-Axis Max) for 2D. In 2D, this will be the width of the resulting rectangle.
To define the region using the mouse, click on the
Select Points with Mouse button. Using the right mouse button select the input coordinates from a display of the grid or solution field. After selecting the points, the values will be loaded automatically into the appropriate fields in the panel. See Section
28.3 for details about mouse button functions.
If you want, you can edit these values before marking or adapting.
To define a hexahedron or quadrilateral, select the two points of the diagonal in any order.
To define a sphere or circle, first select the location of the centroid and then select a point that lies on the sphere/circle (i.e., a point that is one radius away from the centroid).
To define a cylinder, first select the two points that define the cylinder axis and then select a point that is one radius away from the axis.
