Intensity Command

The Intensity command is used to map levels in a gray-scale BMP File image to different types of material points or to different material initial conditions in an MPM analysis. For FEA calculations, it is used to material the image to different types of materials to assign to mesh elements. When a second mask BMP File is used to determine material angles, another Intensity command is used to map intensities to an angle. The two forms are:

Intensity (id),(imin),(imax),<(prop),(value)>,...

or

Intensity "angles",(imin),(imax),(angle1),(angle2)

where:

Notes

  1. Multiple Intensity commands in a single BMPRegion block can be used to define a composite material or to define regions with different initial conditions.
  2. A particle or mesh location corresponding to a gray scale level not covered by any Intensity command range, will be left empty in the grid or mesh.
