ALPHAD, VALUE
Defines the mass matrix multiplier for damping.
Defines the mass matrix multiplier, α, for damping. One form of the viscous damping matrix [C] is given by α[M] + β[K], where [M] is the mass matrix and [K] is the stiffness matrix. Damping is not used in the static (ANTYPE,STATIC) or buckling (ANTYPE,BUCKLE) analyses.
TIME, TIME
Sets the time for a load step.
DELTIM, DTIME, DTMIN, DTMAX, Carry
Specifies the time step sizes to be used for this load step.
OUTRES, Item, Freq, Cname
Controls the solution data written to the database.
KBC, KEY
Specifies stepped or ramped loading within a load step.
AUTOTS, Key
Specifies whether to use automatic time stepping or load stepping.
SFA, AREA, LKEY, Lab, VALUE, VALUE2
Specifies surface loads on the selected areas.
LKEY is ignored if the area is the face of a volume region meshed with volume elements.
For example:
asel,s,loc,z,0
sfa,all,1,pres,10000
LSWRITE, LSNUM
Writes load and load step option data to a file.
Number to be assigned to the load step file name for identification purposes. Defaults to 1 + highest LSNUM used in the current session. Issue LSWRITE,STAT to list the current value of LSNUM. Issue LSWRITE,INIT to reset to 1. The load step file will be named Jobname.Sn, where n is the specified LSNUM value (preceded by "0" for values 1-9). On systems with a 3-character limit on the file name extension, the "S" is dropped for LSNUM > 99.
LSSOLVE, LSMIN, LSMAX, LSINC
Reads and solves multiple load steps.
NSOL, NVAR, NODE, Item, Comp, Name
Specifies nodal data to be stored from the results file.
For example:
nsol,2,146,u,z,UZ146
PLVAR, NVAR1, NVAR2, NVAR3, NVAR4, NVAR5, NVAR6, NVAR7, NVAR8, NVAR9, NVAR10
Displays up to ten variables in the form of a graph.
/AXLAB, Axis, Lab
Labels the X and Y axes on graph displays.
/GRID, KEY
Selects the type of grid on graph displays.
/GROPT, Lab, KEY
Sets various line graph display options.
For example:
/gropt,cgrid,on
