Highlights

 

hmtoggle_arrow1Drawbeads Contact (TYPE8)

MPI parallelization for TYPE8 contact: very good scalability has been reached, allowing to significantly reduce solution time for large models using TYPE8 contact.

 
hmtoggle_arrow1Hill Material Laws Input (LAW32, LAW43 and LAW73)
•Iyield0 flag: optional input for yield stress (either average or orthotropic direction-1 stress).
hmtoggle_arrow1Rigid Body Motion (Springback Computation)
•/IMPL/QSTAT/MRIGM: Displacement results (after springback) are now more user-friendly because of removal of rigid body motion

 
hmtoggle_arrow1Thermal Options

Contacts TYPE7 and TYPE21

•Friction coefficient as a function of temperature

 

Tied Contact (TYPE2)

•Thermal conduction is now supported

 

Edge to Edge Contact (TYPE11)

•Thermal conduction and radiation are now supported

 
hmtoggle_arrow1Equivalent Stress Output for All Material Laws
•/ANIM/SHELL/SIGEQ and /ANIM/BRICK/SIGEQ write equivalent stress as an output in ANIM files

 
hmtoggle_arrow1Contact TYPE21
•DT/INTER/STOP option is now supported for contact TYPE21

 
hmtoggle_arrow1Initial State File (.sta)
•In multi-stage forming, it is necessary to keep constraints given to the blank in any of the forming steps. These constraints are stored in the .sta file in the form of comments and can be used for the next forming stage.
•Thickness is written along with element connectivity: this allows pre-processors to compute mass, penetrations checks, etc.

 
hmtoggle_arrow1Resolved Issues
•Incorrect temperature results for solid
•Implicit with MUMPS solver does not converge with more than 1 SPMD domain
•Specific heat is not computed correctly if mesh adaptivity is activated
•Possible MUMPS solver failure on Windows with Time step limit error (while memory on computer is insufficient)
•/ANIM/SHELL/THIN: thinning is not carried from stage 1 to stage 2
•/ANIM/SHELL/PHI: possible wrong output values for PHI angle
•Strain Tensor values are zero in A00 file (affects version 14.0 only)
•Segment termination on 13.0 but works fine in 12.0.210
•/STATE/ORTH_LOC, /INISH3/ORTHL: incorrect output values in .sta file
•/INTER/TYPE21: thermal conductance does not work with solid elements
•Wrong output values in .sta file in /INISH3/ORTH_LOC with Ish3n=31
•Implicit: possible starter failure with "s_14.0_win64 a cesse de fonctionner”
•Issue in writing/reading .sta file with TETRA4 elements
•Convection + Tstop + SPMD: possible incorrect temperature values
•/ACTIV does not work with /GRBEAM/BEAM
•/ACTIV: possible wrong temperature output
•/INTER/TYPE21: possible starter failure with ABNORMAL ERROR when GapMax is used
•/DT/THERM: nodal and elementary thermal time step for solid elements are inconsistent
•Starter crashes with Izip=1 in /STATE/STR_FILE and if GZIP is not installed on the computer
•Possible Engine failure when LAW57 (Barlat3) and AMS are used.
