Subroutine Type

Utility/Data Access

Definition

Used in conjunction with UCOSUB to define the part states in a user-defined constraint.

Use

This function is called by UCOSUB.

Calling Syntax

Fortran

CALL UCOVAR(ID, NPMS, IPMS, NVARS, IVARS)

C

c_ucovar(id, npms, ipms, nvars, ivars)

Python

py_ucovar(id, ipms, ivars)

MATLAB

m_ucovar(id, ipms, ivars)

Input Arguments

[integer] ID

The identifier of the corresponding user defined constraint element
(Constraint_UserConstr) that is invoking UCOSUB.

[integer] NPMS

The total number of elements in the array ipms.

[integer] IPMS

An array containing part IDs for the variable types in the array IVARS.  Arrays LPMS and IVARS must be of same length.

[integer] NVARS

The total number of integer codes in array IVARS.  NVARS must be equal to NPMS.

[integer] IVARS

An array containing integer codes to identify the variables involved in the constraint as described below.

Integer Code

Meaning

11

Part center of mass X displacement with respect to ground.

12

Part center of mass Y displacement with respect to ground.

13

Part center of mass Z displacement with respect to ground.

111

X component of the axis vector U1 with respect to ground.

112

Y component of the axis vector U1 with respect to ground.

113

Z component of the axis vector U1 with respect to ground.

211

X component of the axis vector U2 with respect to ground.

212

Y component of the axis vector U2 with respect to ground.

213

Z component of the axis vector U2 with respect to ground.

311

X component of the axis vector U3 with respect to ground.

312

Y component of the axis vector U3 with respect to ground.

313

Z component of the axis vector U3 with respect to ground.

Here U1, U2, and U3 are unit vectors pointing along the positive X, Y, and Z axes of the part principle axes.

Output Values

None.
