On Abaqus, I have a macroscopic viscoelastic beam build in on one end with an array of microscopic, magnetic beads fixed to the surface of the beam. I need to model how much deflection will be at the tip. I used the linear pattern tool to make the beads on the surface, searched for contact points and tied them down, but an error appears saying that the volume of the beads are too small. I have tried scaling the model but there is still a message saying that the volume is too small. How do I fix the volume issue?
Hello Steven,
There is a possibility that the elements are penetrating the neighboring surfaces (due to mesh discretization).
There is also a possibility that the adjust=yes definition on the tie constraint definition is adjusting the slave nodes which in turn is distorting the mesh.
Switch off the tie constraint definition, run a datacheck and see if it runs to completion. Its either the tie constraint definition or poor mesh that's causing the problem.
