====== 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 [[com: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 [[com:MSET]]) or may be used to define soil layering or halfspace properties for the ACS SASSI [[SASSI:SITE]] module.
