LAYERP26, NUM
Specifies the element layer for which data are to be stored.
The default is N = 1, meaning that
results data are from the “first” layer. If KEYOPT(8)
= 0, “first” layer actually means the bottom of the bottom
layer and the top of the top layer.
Defines the element layer for which results data are to be stored for postprocessing. Applies to stress and strain data for layered elements BEAM161, SHELL163, SHELL181, SOLID185, SOLID186, SOLSH190, SHELL208, SHELL209, SHELL281, REINF265, and ELBOW290.
The SHELL command can be used (for shell elements) to specify a location (TOP, MID, BOT) within the layer for selection on the ESOL command. Transverse shear stresses for MID are linearly averaged from TOP and BOT, and do not reflect a parabolic distribution. Setting KEYOPT(8) = 2 for SHELL181, SHELL208, SHELL209, SHELL281, and ELBOW290 writes the mid-surface values directly to the results file and yields more accurate values than linear averaging.
That this command cannot be used for energy output, as energy is a per-element quantity.
When using the LAYERP26 command with SHELL181, SOLID185, SOLID186, SOLSH190, SHELL208, or SHELL209, KEYOPT(8) must be set to 1 (or 2 for SHELL181, SHELL208, SHELL209, SHELL281, and ELBOW290) in order to store results for all layers.
For the ANSYS LS-DYNA product, this command works differently than described above. For SHELL163 and BEAM161, you must first use EDINT during the solution phase to define the integration points for which you want output data. Be aware that the output location for SHELL163 data is always at the integration point, so "top" and "bottom" refer to the top or bottom integration point, not necessarily the top or bottom surface. For more information, see the ANSYS LS-DYNA User's Guide.
In POST26, the ESOL data stored is based on the active LAYERP26 specification at the time the data is stored. To store data at various specifications (for example, layers 2 and 5), issue a STORE command before each new specification.
