Input Arguments
Welcome to Adams/Solver Subroutines
area A double-precision variable that specifies the value of the contact area.
dflag A logical variable that Adams/Solver sets to true when it calls CNFSUB to
evaluate the partial derivatives of the specified functions. Otherwise,
Adams/Solver sets the dflag argument to false.
gap A double-precision variable that specifies the value of the contact penetration.
gap ≥ no penetration
gap < 0 penetration
gapdot A double-precision variable that specifies the first time-derivative of the gap.
gapdot ≥
0 gap is increasing (penetration is decresing)
gapdot < 0 gap is decreasing (penetration is increasing)
gapdotdot A double-precision variable that specifies the second time-derivative of the gap.
gapdotdot >= 0 gapdot is increasing
gapdotdot < 0 gapdot is decreasing
id An integer variable that provides the identifier of the CONTACT statement
requesting information from CNFSUB. From the identifier, Adams/Solver
automatically recognizes other information (such as the par argument) that is
available in the corresponding statement.
iflag A logical variable that Adams/Solver sets to true when it needs the functional
dependency information from CNFSUB. Functional dependencies are
established with the same calls to SYSARY and SYSFNC that are later used to
compute the values of the CONTACT components (see SYSARY and
SYSFNC). If the iflag argument is false, the values of the user-defined
expressions are computed.
loci A double-precision array that specifies the vector from the reference marker of
the CONTACT I Geometry (IGEOM) to the contact point on IGEOM. Expressed
in the coordinate system of the reference marker of IGEOM.
locj A double-precision array that specifies the vector from the reference marker of
the CONTACT J Geometry (JGEOM) to the contact point on JGEOM.
Expressed in the coordinate system of the reference marker of JGEOM.
ni A double-precision array that specifies the surface normal vector of the
CONTACT I Geometry (IGEOM) at the contact location. Expressed in the
coordinate system of the reference marker of IGEOM.
nj A double-precision array that specifies the surface normal vector of the
CONTACT J Geometry (JGEOM) at the contact location. Expressed in the
coordinate system of the reference marker of JGEOM.
