Dear All,
I hope all feel so fine with your simulations.
Recently, I am simulation a rolling process with a very high dynamic speed (around 5 m/s). Hence, the model is quite dynamic and not Quasi-static.
I use Abaqus Explicit for this simulation. The structure is composite material including several layers with different material properties. In this case, I am using ''Cohesive Surface'' definition as the surface interaction between different layers.
I have a big problem and there is an error during the simulation process so called:
''the ratio of deformation speed to wave speed exceeds 1.0000 in at least one element''.
I tried to find a solution for this problem such as:
Larger mesh ……. But the larger mesh decreases the solution accuracy.
Have you ever seen any solution for this case?
In this respect, may I imagine to let me know please if you have already any hints or solution for this problem.
Thanks for your attention.
Kind regards,
Hassan
