Solid
- When scalar data are represented as a solid, all active cells in the
grid are colored by mapping scalar values to the color bar.
- Inactive cells, if present in the grid, are excluded.
- Because the solid is rendered as opaque, only the
exterior surface is visible.
- The interior of the solid can be examined by
thresholding and
cropping.
Model Viewer provides 3 coloring schemes:
(How to specify the coloring scheme)
- Blocky: Each cell has a uniform color according to the
nodal value for that cell. This scheme is available only for finite-difference
models (such as MODFLOW) but not for finite-element models (such as SUTRA).

- Smooth: Nodal values are interpolated to yield scalar
values that vary smoothly from one node to another. Consequently, the colors
vary smoothly through the solid.

- Banded: The solid is divided by isosurfaces into a
discrete number of bands. Each band has a uniform color.
