CONVERGED WITH 2 ITERATIONS, |du|/|u|,|r|/|r0|,|dE|/|E|= 0.5915 0.4747E-01 0.1166
Each iteration contains a printout of the normalized (L2 Norm) initial values (iteration
zero) or relative one of displacement, force residual and energy. So
|du|/|u|
is relative residual in displacement,
|r|/|r0|
is relative residual in force and
|dE|/|E|
is relative residual in energy.Stiffness Matrix Setup
*--------- STIFFNESS MATRIX SETUP ---------* SYMBOLIC DIM : ND = 164202 NZ = 6047160 NB_MAX = 96 FINAL DIM : ND = 154605 NZ = 5652417 NB_MAX = 96
ND
- Dimension of the stiffness matrix (number of DOFs)
NZ
- Number of non-zero values of the strict triangular matrix (only
ND+NZ
values are stored due to the symmetry of matrix) NB_MAX
- Maximum number of connected nodes in the model
Radioss eliminates all dependent nodes (this process is called
condensation) before resolution, and so the
SYMBOLIC
and FINAL
dimensions correspond
respectively to the matrix dimension before and after condensation.

- CPU information If the keyword /MON/ON is defined in the Radioss Engine input file (_0001.rad), some detailed information regarding CPU processing time information for the implicit scheme is printed in the .out file:

- Pre-conditioning matrix (if iterative solver is used)
IMPL.SOLV
- For the resolution of {x}=[K]-1{b}
The numerical values represent time.
