Changelog

[0.4.2.4] - TBR

  • Corrected Axisymmetric frictional contact
  • Added GMT material to inpt
  • Begining to add hot compression example with GMT mat
  • Corrected yield stress calc with correct Initial Temp
  • Added fnuction reading for contact surfaces

[0.4.2.4] - 20240430 - 2599719a5437b4c33f77fc5487690a9b40f8b7a2

  • Added Axisymmetry working OK (do not put left box at zero, remains corrections at axis).
  • Reading some LS-Dyna Inputs.
  • Penging AxiSymm contact validation

Input File

  • Added Angular Velocity reading
  • Added Johnson Cook Damage models
    • First the one from Islam 2017

Solver

  • Fixed a crash introduced with initial velocity (vector not dimensioned).

[0.4.2.3] - 20240104 - Hot Fixes

Solver

  • Fixed Initial Yield Stess (bug with Johnson Cook Solver)
  • Parallelized Kernel Gradient Correction

[0.4.2.1] - 20230822 - Hot Fixes

Solver

  • Deprecated KickDrift (was erroneously the default coupled thermal-mechanical)

Input File

  • Now "Thermal" is default Leapfrog thermal mechanical

[0.4.2] - 20230818 - Bug Fixed and Improvements

Solver

  • CORRECTED Randles and Libersky Central Differences (Leapfrog form) solver. Now accepts as Fraser Solver (fixed ts) a CFL up until 1 (default 0.6) in some cases. This is a MAJOR ISSUE since allows for same CFL as Fraser, but works also with variable step size (Fraser works only with constant time steps). Changed default to this solver.

Input File

  • Fixed Amplitude reading (it was an error).
  • Added amplitude function to standard velocity BC (no contact)

Deprecated

  • KickDrift Randles & Libersky Solver (which was in Verlet Form), was a low CFL

[0.4.1] - 20230725

Solver

  • Now reading constant thermal properties and initial conditions. First thermal-mechanical example ready.
  • Fixed Friction Stir Welding example (greater particle density results in not so negative temp at the begining)
  • Added input reading details (to know in which vars exists an input error)
  • Randles and Libersky variable time step integrator working

Input File

  • Nb frequency update option on input
  • Changed Sjohnson Cook constant order
  • Added Cylindrical grid option in input

Deprecated

  • Original Simultaneous Solver (All vars calculated at same time)

[0.4.0] - 2023-02-03

Core

  • Structural , thermal and coupled solver.
  • Fraser, Leapfrog, Verlet and Differential KickDrift time integration working.
  • Bilinear, Hollomon and Johnson Cook materials.
  • Frictional Wang contact.
  • Working accumulated frictional contact Work, external forces Work and plastic dissipated Work.

Input File

  • Wang Frictional contact algorithm working, giving same results that FEM solvers.
  • First imput file reader: working only for structural problems.
  • Input Boundary conditions of velocity and zones.
