Argument	Format	Description
`NEL`	Integer read only scalar	Number of elements per group. In Radioss Engine subroutines, the element data are treated by groups for vectorization. This argument is machine-dependent and set by Radioss.
`NUVAR`	Integer scalar	Number of extra variables needed for each solid element in SINInn or SUSERnn.
`IOUT`	Integer read only scalar	Output file unit (L100 file).
`IPROP`	Integer read only scalar	Property number.
`IMAT`	Integer read only scalar	Material number.
`SOLID_ID`	Integer read only scalar	Array of size `NEL` containing solid element ID.
`EINT`	Float array write only	Array of size `NEL` containing initial total internal energy.
`VOL`	Float array read write	Array of size `NEL` containing initial element volumes. The incoming value is computed with one integration point, which can be recomputed.
`UVAR`	Float array read write	Array of size NEL*NUVAR containing user element variables.
`OFF`	Float array read write	Array of size `NEL` containing deleted element flags. 0 If the element is OFF 1 If the element is ON
`RHO`	Float array read write	Array of size `NEL` containing initial densities.
`SIG`	Float array read write	Array of size 6*`NEL` containing initial stress tensors SX, SY, SZ, SXY, SYZ, and SZX.
`XX1`	Float array read only	Array of size `NEL` containing initial X coordinate at node 1 in the global frame.
`VX1`	Float array read only	Array of size `NEL` containing initial X velocity at node 1 in the global frame.
`VRX1`	Float array read only	Array of size `NEL` containing initial X velocity at node 1 in the global frame.
`MAS1`	Float array read only	Array of size `NEL` containing mass at node 1.
`INN1`	Float array read only	Array of size `NEL` containing inertia at node 1.
`STIFM`	Float array write only	Array of size `NEL` containing element translational stiffness in time step computation.
`STIFR`	Float array write only	Array of size `NEL` containing element rotational stiffness in time step computation.
`VISCM`	Float array write only	Array of size `NEL` containing element translational viscosity in time step computation.
`VISCR`	Float array write only	Array of size `NEL` containing element rotational viscosity in time step computation.
