Applying displacement relative to the deformed configuration and not the initial configuration

thread799-460812

Applying displacement relative to the deformed configuration and not the initial configuration

Applying displacement relative to the deformed configuration and not the initial configuration

(OP)
Hi Everyone,

I am running a model that has a lot of bending. I am performing a restart analysis to adjust the final position of the part after the bending steps. In the restart analysis, I am refining the position of the bent part by adjusting the position of some nodes using a displacement boundary condition. However, when I specify the displacement, the displacement value input is relative to the position of the node in the undeformed configuration which makes it difficult for me to know how much to displace the required node. Is there a way to specify the displacement relative to the deformed part in a given step rather than relative to the undeformed state? I have tried using OP=New but it doesn't work for me.

Thanks for the help!

Paul

RE: Applying displacement relative to the deformed configuration and not the initial configuration

Use a velocity boundary condition. Works also in static analysis.

RE: Applying displacement relative to the deformed configuration and not the initial configuration

Instead of restart try using import capability with "Update reference configuration" option turned on. This should give you the desired effect.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
