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.
 
subroutine m_fstr_nonlinearmethod::fstr_newton_contactalag (cstep, hecmesh, hecmat, fstrsolid, fstrparam, restart_step_num, restart_substep_num, sub_step, ctime, dtime, infoctchange)
 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 )
 
subroutine m_fstr_nonlinearmethod::fstr_newton_contactslag (cstep, hecmesh, hecmat, fstrsolid, fstrparam, fstrmat, 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.
