The TRANS function transforms an arbitrary vector function expression represented in the coordinate system of marker j to the coordinate system of marker i.
Format
TRANS(exp,i[,j])
Arguments
exp | An arbitrary vector function expression. |
i | The marker whose coordinate system the expression, exp, is to be represented. |
j | The marker in whose coordinate system the expression, exp, is specified. If not specified, the expression, exp, is assumed to be specified in the global coordinate system. |
Examples
VFORCE/1, I=1, JFLOAT=2, RM=3, FXYZ=VXYZ(i,j,k)
VFORCE/2, I=1, JFLOAT=2, RM=3, FXYZ=TRANS(VXYZ(i,j),k)
VFORCE/3, I=1, JFLOAT=2, RM=3, FXYZ=TRANS(VXYZ(i,j,l),k,l)
Variables 1, 2 and 3 are synonymous. They all specify a vector force law that is equal to the velocity vector of marker i with respect to marker j, represented in the coordinate system of marker k.
