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:

*do,ii,1,#steps,1
Increment displacement with 10 micron
Evaluate reaction forces
if(reaction forces < 10)
continue
else
break loop
end
*enddo

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.
