      I tried but failed to run my first strong-coupling fluid structure interaction (FSI) simulation using the LS-DYNA ICFD solver.  Does anyone know what could trigger the following LS-DYNA error message?

       *** Error 120003 (ICFD+3)
           ICFD::Node without material 0

      Hi! this error involves SystemCoupling service, I got this sometimes when restarted FSI run.
      Check that you correctly specified FSI`s (interfaces) in Fluent and Mech. try to reboot,  swichoff firewall / antivirus. Test FSI tutorial if it runs well.

       

      This may help you,

      Hello Xuejun,

      Make sure you assign a material to all your ICFD parts. If you don't, you will most likely get the above error message.
