This command is used to perform the analysis.
| analyze $numIncr <$dt> <$dtMin $dtMax $Jd> |
| $numIncr | number of analysis steps to perform. |
| $dt | time-sep increment. Required if transient or variable transient analysis |
| $dtMin $dtMax | minimum and maximum time steps. Required if a variable time step transient analysis was specified. |
| $Jd | number of iterations user would like performed at each step. The variable transient analysis will change current time step if last analysis step took more or less iterations than this to converge.
Required if a variable time step transient analysis was specified. |
RETURNS:
0 if successful
<0 if NOT successful
EXAMPLE:
set ok [anlayze 10]; # perform 10 static analysis steps
set ok [analyze 2000 0.01]; # perform 2000 transient time steps at 0.01 increments
