Forming
Forming

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

•	Iyield0 flag: optional input for yield stress (either average or orthotropic direction-1 stress)

•	/IMPL/QSTAT/MRIGM: Displacement results (after springback) are now more user-friendly because of removal of rigid body motion

•	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.

•	Contact TYPE21: Support Thermal heat transfer through TYPE21 contact to solid elements behind it

•	/ANIM/SHELL/SIGEQ and /ANIM/BRICK/SIGEQ write equivalent stress as an output in ANIM files.

•	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 .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.

•	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.

•	No strain/stress in animation for thermal expansion test

•	Output strains are not consistent with Ismstr=11

•	Convection does not apply if deactivated elements are surrounding an element

•	Error with PROP/CONNECT and INIBRI/STR_F: Stress and Strain tensors are now written correctly into the STA files for property /PROP/CONNECT and the sta files may be used for initialization in starter

•	LAW4 + PROP/SOLID : temperature has no effect on stresses

•	Thickness defined in INISHE/THICK is not taken into account
