*RELA
i1, r1
i1: i*4: number of iterations. Default 0
r1: r*8: Scaling factor. Default 1.d00
This card allows for the step size of the Newton-Raphson solver to be scaled by r1 for i1 iterations. The purpose of this option is to stabilize the solver and/or accelerate convergence.
Thermal analysis should converge using 1, 0.4 Excessive non-linearities caused by material properties or using *LATE may require using more relaxation iterations, i.e. 2, 0.4.
Mechanical analysis should converge 1, 0.2 This is the default value used by GUI. If the simulation does not converge, increase the number of iterations, i.e. 2, 0.2
