Exitflag variable in APDL

    • antud

      Hello everyone,

      I'm doing a simulation of snap-through behaviour of a buckled beam/flexure. I am trying to obtain the force-deflection behaviour in both directions: from knee-up to knee-down and vice versa. In order to do this, I use a displacement-controlled analysis in the form of a loop. In this way, you're not required to set the target amount of displacement. The loop is as follows:

      Increment displacement with 10 micron
      Evaluate reaction forces
      if(reaction forces < 10)
      break loop

      However, when not using the stabilize command, this gives some convergence errors.

      I was wondering whether it is possible to have the simulation return and store a variable upon divergence, something like an exitflag I can access when the simulation does not converge. Does anyone happen to know whether this is possible?

      Thank you in advance.
