CONVERGE 2.4.19 datecode 20.06.2018

ONVERGE 2.4.19 is a minor release that includes enhancements and bug fixes.
Solver
Bug fix:  Fixed  an  error  that  caused  CONVERGE  to  crash  in  simulations  with  bothenergy_solver_f lag=  2  (i.e.,  the  total  energy  solver)  and  species_dif f usion_model  =  1  ininputs.in.
Bug fix:  The steady-state solver imposes upper and lower limits on sensible  internal  energy(sie),  but  CONVERGE  did  not  correctly  determine  these  limits  for  cases  with  tabulatedfluid properties (tabular_f luid_prop_f lag = 1 in inputs.in). This bug has been fixed.
Bug fix:  Fixed a bug that caused occasional  crashes  for  simulations  with  both  the  MUSCLscheme and at least one FLOW_THROUGH boundary.
Bug fix: Previously the SOR algorithm did  not  always  exit  correctly  due  to  an  error  in  theomega cutting mechanism. This bug has been fixed.
Input
Bug fix:  Fixed  a  bug  related  to  bound_or_vector  in  dynamic.in.  Previously  CONVERGEchecked for a boundary ID even when bound_or_vector = 1, and this erroneous check couldcause the simulation to crash.
Bug fix:  If  there  is  an  imbalance  of  elements  between  the  reactants  and  products  in  anychemical  reaction,  CONVERGE  now  prints  a  warning  message  to   alert   you   to   theimbalance. Previously a bug prevented this warning from being written.
Bug fix:  For  NASA  7-formatted  therm.dat  files,  CONVERGE  now  verifies  the  upper  andlower  temperature  limits.  Previously  this  check  did  not  exist,  which  sometimes  led  to  anout-of-bounds error.
Output/ Post-Processing
Enhancement:  CONVERGE  now  writes  more  detailed  screen  output,  including  the  meanand standard deviation of the monitored variables, for the steady-state monitor.
Enhancement:  CONVERGE  writes  additional  Reynolds  stress  quantities  to  turbulence.out.For  simulations  that  have  a  different  turbulence  model,  these  quantities  will  have  a  valueof -1.
Bug fix: For parallel simulations, if some processors did not have wall cells for a  given  wallin wall_output.in, CONVERGE would crash. This bug has been fixed.
Bug fix: Some  CONVERGE  2.4.18  simulations  that  contained  monitor  points  and  thatwere run on a Windows machine crashed. This bug has been fixed.
Bug fix:  Fixed  a  bug  that  caused  incorrect  energy  residuals  for  solid  regions  to  be  writtento residuals.out.
Bug fix:  Fixed  a  bug  that  caused  the  firstpost*.out  file  to  have  the  wrong  time  (in  itsfilename) for steady-state cases that had been restarted.
Enhancement: Added the Carreau model for non-Newtonian fluids.
Enhancement: CONVERGE  can  now  simulate  compressible  composite  liquid   species.Previously composites were not allowed for compressible liquids.
Boundaries
Enhancement:  CONVERGE  now  automatically  issues  a  warning  regarding  boundariesthat  should  be  set  as  RELOFT  boundaries.  In  addition,  RELOFT  boundaries  now  supportnormal motion via the new depend keyword.
Bug fix:  For  moving  WALL  boundaries  with  a  1D  CHT  temperature  boundary  condition,CONVERGE did not  always  maintain  the  correct  coordinates  for  points  on  the  boundary.This bug led to incorrect temperatures in the post*.out files.
Bug fix:  Fixed a bug that  caused  some  cases  with  both  INTERFACE  boundaries  and  fixedembedding at the INTERFACE to crash.
Bug fix:  Fixed  a  memory  access  problem  that  caused  CONVERGE  to  crash  when  aFLOW_THROUGH boundary coincided with a processor boundary.
Bug fix: Added  checks  and  a  warning  message  if  the  surface  from  a  spatially  varyingboundary condition is offset from the corresponding boundary.
Regions and Initialization
Bug fix:  Fixed a bug that caused some cases to crash after region initialization.
Spray
Bug fix:  For simulations with both the ELSA model and the cavitation model,  CONVERGEdid not correctly identify the liquid species. This bug has been fixed.
Bug fix:  Fixed a bug that caused some simulations with parcel_evap_model= 0 to crash.
Bug fix:  The  LISA  breakup  model  gave  incorrect  spray  parcel  diameters  for  cases  thatinvoked the steady-state solver. This bug has been fixed.
Bug fix:  Fixed  an  error  that  very  slightly  affected  the  evaporated  mass  calculation  in  the Discretized Temperature Model.
Combustion and Emissions
Enhancement: CONVERGE  now  rereads  the  issim.in  file  during  a  restart  if  the  start  timefor the restarted simulation is prior to the start time of the spark specified in issim.in.
Enhancement: The  ECFM  combustion  model  can  now  run  cases  with  multi-componentfuels.
Bug fix: Fixed  several  bugs  in  the  detailed  decomposition  of  urea  model.  These  fixesimprove  the  computational  efficiency  of  this  model  and  make  it  more  physically  realistic.Results may change slightly.
Bug fix:  Fixed  a  bug  that  led  to  incorrect  soot  predictions  from  the  PM  and  PSM  detailedsoot models for simulations that also used the user_mech_rate.c user-defined function.
Bug fix: Fixed some bugs in the ECFM combustion model that caused incorrect  flamespeed values.
CHT
Bug  fix:  Fixed  a  bug  that  caused  incorrect  output  temperatures  (written  to  the  post*.outfiles.) after super-cycling.
Bug fix: Previously CONVERGE erroneously allowed any type  of  boundary  to  be  assignedto  the  super-cycling  boundary  group,  and  this  error  occasionally  led  to  crashes.  Newchecks  have  been  added  to  ensure  that  each  super-cycling  boundary  is  INTERFACE  orWALL (if WALL, the boundary must have a temperature boundary condition  of  convectionor Neumann)  and  that  both  the  f orward  and  reverse sides  of  an  INTERFACE  boundary  areassigned to the same stream.
VOF
Bug fix: Fixed several bug related to mass conservation for incompressible VOF modeling.
FSI
Enhancement: The FSI spring model can now accommodate a  variable spring constant.  Toinvoke  this  new  option,  specify  a  file  name  instead  of  a  number  for  spring_constant  inf si_spring.in and include a file that contains the spring constant data.
GT-SUITE
Enhancement: CONVERGE now calculates pressure boundary  conditions  by  interpolatingbetween  GT-SUITE's  supplied  pressure  data  and  CONVERGE's  region-average  pressurefor gti_flag=3 and 13. This enhancement  is  an  extension  of  the  GT-SUITE  enhancement  in 2.4.18.
UDF
Enhancement: The CKWYP routine in user_mech_rate.c has been renamed.
Bug fix: Fixed a bug  in  the  user_combust_rif .c routine. This  bug  prevent  scalar_diss_rate.outfrom being written and it may have led to incorrect data in thermo.out.
Bug fix: Fixed  a  bug  in  the  user_points_data.c  routine  that  caused  incorrect  equivalenceratio data for the UDF monitor points.
Bug fix: CONVERGE incorrectly invoked  user_spray_colide.c (instead  of  the  correspondingsubroutine in the main code) when user_coalesce_f lag = 0 in udf .in. This bug has been fixed.
Bug fix:  Fixed a bug in the Windows UDF code that caused a problem with the libraries.
