L Command

L,<nm>,<thick>,<weight>,<pveloc>,<sveloc>,<pdamp>,<sdamp>

defines the soil layer number <nm> with thickness <thick>, specific weight <weight>, P-wave velocity <pveloc>, S-wave velocity <sveloc>, P-wave damping ratio <pdamp>, and S-wave damping ratio <sdamp>.

For embedded models, the layers defined using this command should in the same order as is used in the TOPL command. Layers should not be repeated in the TOPL command for embedded models.

Note: Soil layers may be assigned to excavated soil elements (see MSET) or may be used to define soil layering or halfspace properties for the ACS SASSI SITE module.
