Hello,
I think my challenge is within the range of this topic. I have a structure which is in force balance, well suited for linear FEA either by manual 3 point constraint or by inertia relief. However when continuing with plasticity and LDA (Creo 3.0) the LDA causes (of course) a small disturbance in this balance resulting in unacceptable peak stresses and plastic deformations at the point constraints. It would be nice to address this by taking reaction force measures on the constraints and use them as input on a to-be-defined compensation force and restore the balance in this way. For this the measures would need to be accessable in relations AND the force definition would need to be updated every time step. For now I can compensate by hand by running quick checks and plotting the graphs of these measures but it would be nice to feedback intermediate results into the running analysis.
Best regards,
Victor
