Arrow Positioning
Under Arrow Positioning, first select a Placement of the arrows:
For Arrow Surface in 3D plot groups and Arrow Line in 3D and 2D plot groups:
Under Positioning, first select a Placement: Gauss points, Mesh nodes, Uniform, or Uniform anisotropic.
Select Gauss points to position the arrows in the elements’ Gauss points when a solution is available. Also specify the order of the Gauss points in the Gauss point order field (default: 1). A higher order increases the arrow density in each element.
Select Mesh nodes for arrows positioned in the mesh element nodes (that is, more densely placed arrows where the mesh density is high).
Select Uniform (the default) for arrows positioned uniformly on the surface. Then enter the number of arrows to plot in the Number of arrows field (default: 200).
Select Uniform anisotropic to position the arrows using an anisotropic density (that is, more arrows in some directions than in others). In addition to entering the number of arrows to plot in the Number of arrows field (default: 200), use the x weight, y weight, and (in 3D) z weight fields to give weights for the arrow density in the different directions (using positive scalar weights). The default weights are 1 in all directions. A higher value increases the arrow density in the corresponding direction.
For Arrow Volume in 3D plot groups and Arrow Surface in 2D plot groups:
Under Positioning, first select a Placement: Element centers, Mesh nodes, or Grid (the default):
Choose Element centers to position the arrows in the element centers; if desired, change the value in the Maximum number of points field (default: 100,000).
For Mesh nodes, see above.
For Grid, in the x grid points, y grid points, and z grid points fields, select an Entry method: Number of points or Coordinates:
-
If Number of points is selected, enter the number of Points in each direction (the default is 7 for Arrow Volume plots and 15 for Arrow Surface plots).
-
If Coordinates is selected, enter Coordinates (SI unit: m) or click the Range button () to define a range of values.
