Coordinate System

Choose to plot a (the default) or a :

•

For , choose one of the available coordinate systems from the list. The default is (no coordinate system). The coordinate system directions arrows are red for the first coordinate direction’s basis vector, green for the second coordinate direction’s basis vector, and blue for the third coordinate direction’s basis vector.

•

For , click the button (

) to select an available matrix variable from the list, which includes transformation matrices to and from the added coordinate systems and physical quantities that are tensors, such as the thermal conductivity. Only 2-by-2- and 3-by3-matrices are supported. The selected variable (for example, ht.k) then appears next to the . Each row of the matrix is plotted as a vector. The first row is plotted in red, the second row in green, and the third row, if any, in blue. Click the check box if you want to add a description for the matrix variable. From the list, choose (the default) or . Plotting the vectors as columns can be useful, for example, when plotting the deformation gradient variables in a structural mechanics interfaces. Plotting the deformation gradient’s columns as a triplet of arrows gives a good picture of the local deformation and rotation of the material.

Positioning

For in 3D plot groups and in 3D and 2D plot groups:

Under , first select a : , , , or .

•

Select to position the coordinate system symbols in the elements’ Gauss points when a solution is available. Also specify the order of the Gauss points in the field (default: 1). A higher order increases the coordinate system symbol density in each element. This option is not available for plots in 2D plot groups.

•

Select for coordinate system symbols positioned in the mesh element nodes (that is, more densely placed symbols where the mesh density is high).

•

Select (the default) for coordinate system symbols positioned uniformly on the surface. Then enter the number of symbols to plot in the field (default: 200).

•

Select to position the coordinate system symbols using an anisotropic density (that is, more symbols in some directions than in others). In addition to entering the number of coordinate system symbols to plot in the field (default: 200), use the , , and (in 3D) fields to give weights for the symbol density in the different directions (using positive scalar weights). The default weights are 1 in all directions. A higher value increases the symbol density in the corresponding direction.

For in 3D plot groups and in 2D plot groups:

Under , first select a : , , or (the default).

•

Choose to position the principal stress symbols in the element centers; if desired, change the value in the field (default: 100,000).

•

For , see above.

•

For , in the , , and fields, select an : or :

If is selected, enter the number of in each direction (the default is 7 for Coordinate System Volume plots and 15 for Coordinate System Surface plots).

If is selected, enter (SI unit: m) or click the button (

) to define a range of values.
