  Hello,
  
  I am working on Blow simulation for tank shells on Discovery AIM. i tired to simulate some test cases where the mold is fixed and the parison sheet moves into the shell, but i am unable to solve the physics. Please help.

  Hello Pkulal
  
  Can you please share the concerned project file for investigating the issue? I will send you a secure transfer link for uploading the model. Please send the archived file. Detailed information on archiving the project file can be found in this article.

  Hello Pkulal
  
  Thanks for sending the file. I made following modifications to the model:
  
  1. Increased the viscosity to 50000 PaS
  
  2. Reduced pressure to 0.008 MPa with a negative (-) sign
  
  3. Under Contact 1, changed Mold body side to "Back".
  
  This helped to solve the model. Can you please try it out at your end?

  Hello Naresh,
  
  Hope you are fine.
  
  i have started to do some blow simulations again on some tanks and i have set up the physics based on your suggestions but i am able to solve it partially, after 0.5 sec i am getting some error called "Error in system util module". please help
