Question

Hello
When I modified the subdomain using TimedSubdomainModifier, the displacement continued to increase at each time step. When I use CoupledVarThresholdElementSubdomainModifier modify domain, this will not happen. What causes this? Do you have any good suggestions?

hello

instead of looking at the displacement, look at the subdomain assignments, to make sure the two objects are actually moving the elements the same way

The subdomain assignment is the same for both methods. The subdomain assignment is the same for both methods. Only the displacement is inconsistent. Curiously, after the subdomain modification is complete, test 1 displacement increases while other variables (such as stress) remain unchanged.

Hello, do you know what caused this situation?

[GiudGiud]

We have just updated the element subdomain modifier (last Thursday). So it is worth updating moose and seeing if the behavior is more consistent now

any update on this?
btw I am looking a figure on the use of CoupledVarThresholdElementSubdomainModifier / MeshModifiers if you have a good one I would love to be able to feature it at a coming conference (ANS Winter 2024)
