Hi all,
I’ve run an impact simulation in LS-DYNA where a ship’s bow collides with an offshore monopile. I’m now analyzing the structural damage and deformations, and I’d like to create an animation of the results using ParaView.
However, I’m running into an issue: since the ship is moving during the simulation, and the rigid body motion (translation) is much larger than the actual structural deformations, it becomes difficult to clearly visualize the deformations in the structure itself.
What I would like to do is isolate and visualize only the relative deformations of the ship (i.e., excluding the global displacement due to the rigid body motion), similar to what’s possible in LS-PrePost using the “follow” function. In LS-PrePost, I can select a reference node, and the software displays the deformation of the structure relative to that point, effectively removing the rigid body motion from the view.
I’ve attached two example images: one showing the total displacement (as displayed in both LS-PrePost and ParaView), and another showing the relative structural deformation from LS-PrePost — which is the result I’m aiming to achieve in ParaView.
Total displacement in LS-PrePost and Paraview:
Relative structural deformation in LS-Prepost:
Is there a way to replicate this functionality in ParaView? Any help or tips would be greatly appreciated!
Thanks in advance!
