FK, KPOI, Lab, VALUE, VALUE2
Defines force loads at keypoints.
KPOIKeypoint at which force is to be specified. If ALL,
apply to all selected keypoints [KSEL]. If KPOI = P, graphical picking is enabled and all remaining
command fields are ignored (valid only in the GUI). A component name
may also be substituted for KPOI.
LabValid force label. Structural labels: FX, FY, or FZ (forces); MX, MY, or MZ (moments). Thermal labels: HEAT, HBOT, HE2, HE3, . . ., HTOP (heat flow). Fluid labels: FLOW (fluid flow). Electric labels: AMPS (current flow), CHRG (electric charge). Magnetic labels: FLUX (magnetic flux); CSGX, CSGY, or CSGZ (magnetic current segments). Diffusion labels: RATE (diffusion flow rate).
VALUEForce value or table name reference for specifying
tabular boundary conditions. To specify a table, enclose the table
name in percent signs (%), e.g., FK, KPOI, HEAT,%tabname%). Use the *DIM command to define a table.
VALUE2Second force value (if any). If the analysis type
and the force allow a complex input, VALUE (above) is the real component and VALUE2 is the imaginary component.
Forces may be transferred from keypoints to nodes with the FTRAN or SBCTRAN commands. See the F command for a description of force loads.
Tabular boundary conditions (VALUE = %tabname%) are available
only for the following labels: Fluid (FLOW), Electric (AMPS), Structural
force (FX, FY, FZ, MX, MY, MZ), and Thermal (HEAT, HBOT, HE2, HE3,
. . ., HTOP).
This command is also valid in PREP7.
