number_of_toggles

Number of toggles (37 for Nastran and 0 for OptiStruct).

number_of_integer_values

Number of integer values within the toggles (16 for Nastran and 0 for OptiStruct).

integer_array

The ID of the integer array that contains the additional input parameters. The integer array is created using the *createarray command. This should always be set to 1.

For definitions of the variables, see DOPTRM in the Nastran manual.

[0] = 1
[1] = conv1toggle
[2] = conv2toggle
[3] = convdvtoggle
[4] = convprtoggle
[5] = cttoggle
[6] = ctmintoggle
[7] = dabobjtoggle
[8] = delbtoggle
[9] = delobjtoggle
[10] = delptoggle
[11] = delxtoggle
[12] = desmaxtoggle
[13] = dobj1toggle
[14] = dobj2toggle
[15] = dpmintoggle
[16] = dx1toggle
[17] = dx2toggle
[18] = dxmintoggle
[19] = gmaxtoggle
[20] = gscaltoggle
[21] = igmaxtoggle
[22] = 1
[23] = 1
[24] = 1
[25] = iscaltoggle
[26] = itmaxtoggle
[27] = itrmoptoggle
[28] = itrmsttoggle
[29] = jtmaxtoggle
[30] = jprinttoggle
[31] = jwritetoggle
[32] = 1
[33] = p1toggle
[34] = p2toggle
[35] = ptoltoggle
[36] = stpscltoggle

If an element in the array above is set to zero, the optimization program does not take into account the settings for that variable. If the value for an element is 1, the optimization program uses the values in the arrays below instead of the default values.

The next sixteen elements contain integer parameters:

[37] = APPRCOD
[38] = DESMAX
[39] = IGMAX
[40] = IPRINT
[41] = IPRNT1
[42] = IPRNT2
[43] = ISCAL
[44] = ITMAX
[45] = ITRMOP
[46] = ITRMAST
[47] = JTMAX
[48] = JPRINT
[49] = JWRITE
[50] = METHOD
[51] = P1
[52] = P2

number_of_integers

Integer indicating the size (number of integer parameters, sum of number_of_toggles and number_of_integer_values, 53 for Nastran and 0 for OptiStruct) in the integer array created using *createarray.

double_array

The ID of the double array that contains the additional input parameters. The double array is created using the *createdoublearray command. This should always be set to 1.

[0] = CONV1
[1 ] = CONV2
[2] = CONVDV
[3] = CONVPR
[4] = CT
[5] = CTMIN
[6] = dabobj
[7] = delb
[8] = delobj
[9] = delp
[10] = delx
[11] = dobj1
[12] = dobj2
[13] = dpmin
[14] = dx1
[15] = dx2
[16] = dxmin
[17] = gmax
[18] = gscal
[19] = ptol
[20] = Stpscl

number_of_doubles

Integer indicating the size (number of double parameters, 21 for Nastran and 0 for OptiStruct) in the double array created using *createdoublearray.

Example

To use with OptiStruct:

*createarray 0
*createdoublearray 0
*opticontrolcreate 1 30 0 0 1 2 0 0 1 0.01 0 0 0 0 0 0 0 0 1 0.5 0 0 1 0.5 0 0 0 0 0 0 1 0 1 0

To use with Nastran:

*createarray 53 1 1 0 0 1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 1 1 1 0 1 0 0 0 0 0 1 0 0 0 1 2 1 0 0 0 0 -1 40 2 2 20 0 0 1 0 0

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
