Nogrid pointsBlow release 4.2.0

April 2024

The release of  NOGRID pointsBlow 4.2.0 is available now.

This is new: 

• In case report the heat conductivity was documented wrong. 

• HTML Case Report has only 1 page, the 2nd page was missing. When blank temperature profile is defined, model image is only partially captured.

• Enabling/Disabling the Mold tab corrected (Mold tab was disabled if Compute blow mold was changed from enabled to disabled even Compute blank mold was enabled).
  
  
• The PLUG position changes the temperature curve x-values within the Material Tab-Blank Mold.
  
  
  
  
  
• Improved wall viscosity treatment
  In previous releases the viscosity at walls was cut off if it was too high. For the Hybrid-P1 model in the transition area from free surface to a wall the free surface smoothing was used for the walls, but this smoothing algorithm especially at cold walls results in a unrealistic viscosity increase in the inner fluid. For this reason we've implemented an improved smoothing algorithm for the viscosity at walls.
  
  
• Periodic heat loads or cyclic heating of molds are available now. Starting with a cold or preheated mold, the temperature increases over time with the period of the process until a steady-state temperature distribution is established within the mold.
  
  Figure A: The User can specify the number of heating loops and the accuracy
  
  
  
  Figure B: Intermediate state: Current loop number is 11 and accuracy reached is 76 %.
  
  
  
• Nogrid pointsBlow application can be started within a terminal. Without any parameters a blank GUI is started.
  
  Usage:
  pointsBlow.exe [option] [projectFileName]
  
  projectFileName: read the project with name projectFileName
  -h, --help: displays this text
  -u, --update: reads the project, updates the solver scripts and return, projectFileName is required
  -c, --csv: reads the project, saves the final results contour csv files and return, projectFileName and final results are required
  
  
• The solver of NOGRID pointsblow can now be started directly using following parameters within a terminal:
  
  -h displays the help
  -m=<file> name of model input file
  -n=<file> name of numeric input file
  -l checks and displays the license usage information
  -s displays host name and port number of the license server
  -v displays the version number
  
  
• The position of the equation editor dialog is close to the parent widget now (in previous release the dialog appears in the middle of the screen)
  
  
• If distance blow is active the corresponding IS machine times are disabled
  
  
  
  
  
• The User file and the Settings file is available as an ASCII file if a corresponding license is valid.
• In addition to the velocity its components v_x, v_y and v_z are saved and available within the GUI.
