ALE adaptive meshing for Cutting Simulation

ALE adaptive meshing for Cutting Simulation

ALE adaptive meshing for Cutting Simulation

(OP)
Hi

I simulated 2D cutting in Abaqus/Explicit. it works well. I like to use ALE adaptive meshing to improve my simulation. when I applied ALE meshing to model, It takes too much time and never accomplished and aborted.Size of file.odb is 460 MB without ALE mesh, 30 GB with ALE mesh althougt it is aborted after very small advances around 25 micron, I also wonder why is that.ALE parameters which employed to model:

Frequency=100
Remeshing Sweep per increement=5
initial remeshing sweep=5
ALE adaptive mesh constraint=follow underlying material (workiece all elements)

Meshing and Smoothing:
-----------------------
Priority=Improved aspect ratio
Meshing predictor=current deformation Position
curvature refinement=2
Weights=0.8,0.1,0.1
Advection=second order, element center projection

Can anyone suggest the ALE parameters are applicable to 2D cutting simulation?


2- the other question is;

I set the field output request= every time increment, because ALE meshing make decision for each increemnt.

When I set field output request= evenly spaced time interval;20, simulation could work and accomplished but ALE meshing does not work.

What should I set field output request frequency?, for simulation with ALE meshinng.
