  Hi everyone. I am making a model that glass breaks under pressure. Is it correct to define the load in DEFINE_CURVE and LOAD_BODY_Z ㅁas shown in the picture below? I look forward to your reponse. Thanks.

  Hello,
  DEFINE_CURVE and LOAD_BODY_Z cards are frequently used to define gravity, thus a value of 0.00981 in the load curve. Is the glass breaking under gravity, or is there another load acting on it?
  
  Please let me know.
  
  Thanks,
  Alex

    I tried setting it to 10 instead of 0.00981, but the glass didn't break. Could you help me?

  Hello,
  To apply loads at the specific node/s the keywords *LOAD_NODE/*LOAD_NODE_SET can be used. Please look at the KW II.
