      Hello

      I hope you are doing well.


      I am trying to see crack propagation in dcb using SMART by making an arbitrary crack as following

      Thank you for your question. Can you let me know where your local crack coordinate system is located?

      I recreated a model with similar parameters and I am able to get crack growth using SMART:
      Can you check the ds.dat file for the crack tip node component information (right click on Solution and Open Solver Files Directory); mine has this:

      /com,*********** Done Sending CINT Commands For All Cracks ***********
      /com,*********** Send Crack Growth "SMART Crack Growth" ***********
      *set,cgid,1
      cgrow,new,1! Crack growth set
      cgrow,cid,1! cint id for crack growth
      cgrow,cfcm,NS_ARBCRACK_FRONT! Define crack tip node component
      Also, what are your settings for the Arbitrary crack object?
