Functions/Subroutines

subroutine m_fstr_nonlinearmethod::fstr_newton (cstep, hecMESH, hecMAT, fstrSOLID, fstrPARAM, restrt_step_num, sub_step, ctime, dtime)
 This subroutine solve nonlinear solid mechanics problems by Newton-Raphson method. More...
 
subroutine m_fstr_nonlinearmethod::fstr_newton_contactalag (cstep, hecMESH, hecMAT, fstrSOLID, fstrPARAM, restart_step_num, restart_substep_num, sub_step, ctime, dtime, infoCTChange, conMAT)
 This subroutine solve nonlinear solid mechanics problems by Newton-Raphson method combined with Nested iteration of augmentation calculation as suggested by Simo & Laursen (Compu & Struct, Vol42, pp97-116, 1992 ) More...
 
subroutine m_fstr_nonlinearmethod::fstr_newton_contactslag (cstep, hecMESH, hecMAT, fstrSOLID, fstrPARAM, hecLagMAT, restart_step_num, restart_substep_num, sub_step, ctime, dtime, infoCTChange, conMAT)
 This subroutine solve nonlinear solid mechanics problems by Newton-Raphson method. Standard Lagrange multiplier algorithm for contact analysis is incoluded in this subroutine. More...
