Optistruct -stop nonlinear analysis (LGDISP) at reached Force

Hi at all,

As title, there is a way to run a nonlinear analysis (LGDISP) using an imposed displacement to generate a load on a structure (for example a simple press) and stop the simulation when the analysis at a certain node (reaction force node) reach a specific force value?

Thanks

    by using imposed disp, i can't think in a way of stopping at this force.

    I assme that you don't want to use force based load, due to convergence, am I right?

    Hi Adriano,

    yes I used imposed displacement for stability and convergence

    I don't understand why there isen't a sensor to impose that limitaion

    would be wonderful if hypermesh add some basical control like " if a sensor read this - do that"
