Individual vertex deformation anomalies(these vertices deform too much) in deformed mesh

[Alico10]

Hi!
I am using TriangularFEMForceField and TriangularBendingSpring simulate deformation, I applied some constant force on the mesh,
but after deformation, some abnormal vertices appeared(as stated in the title).
I'm not sure if it's a problem with the physical model parameters or a limitation of the physical model.
If there could be some help, I would greatly appreciate it.
Thank you!

Hi @Alico10

Do you have a simple scene illustrating the problem?
Is this the node on which you are applying the ConstantForceField ?

I can provide an. scn later, but I am currently unable to provide data;
Some points with abnormal deformation appear on nodes subjected to constant force, while others appear on surrounding vertices;
Thank you!

Hi @hugtalbot
This is my demo:

Hi @Alico10

It appears that you use only a surface mechanical model (TrangularFEMForceField and TriangularBendingSprings). Is this on purpose ?
From the picture, the constant force you apply on your object seems to be pretty high compared to the surface stiffness you defined. Are you sure about your mechanical settings?

Cheers
