Re: How to get solution solved faster in 2D Explicit Dynamics
@FernandoTorres I was asking @mji to describe the boundary conditions that must be applied to the nodes on the offset plane. In a 2D model, the Z DOF at each node does not exist. Once you have a 3D model, now you have a node on the Z=0 plane that has a Z DOF. I expect that node must have a boundary condition of Z=0… 
Re: How to get solution solved faster in 2D Explicit Dynamics
@FernandoTorres The mesh must have linear elements so there is no midside node. In that case, every node is on either Z=0 or Z=1 planes. That means the entire body (or two faces) can have a Displacement BC of Z=0 leaving X and Y Free. Some nodes will need to constrain X and Y to be 0 for a Fixed Support and it will be… 
Re: How to get solution solved faster in 2D Explicit Dynamics
When you work with devices that have a dimension of 10 micrometers, and the element size is about 16 nanometers, Explicit Dynamics is not a good place to be. The reason is the minimum time step depends on the element characteristic length. The smaller the length, the shorter the maximum time step and the longer the… 
Re: How to get solution solved faster in 2D Explicit Dynamics
@FernandoTorres In Explicit Dynamics, element removal from the model is automatic. In Transient Dynamics, element removal is not automatic. The article you enjoyed showed you how to do that with a script. This is more work for the user, but may end up taking less time compared with weeks of solution time in Explicit…

Re: How to get solution solved faster in 2D Explicit Dynamics
@FernandoTorres Are you talking about the LSDYNA solver or the AUTODYN solver? An error occurred during the solution that caused it to stop before the end time. These solvers track various energy levels and if a specific type of energy has a threshold to maintain the quality of the solution, the solver will stop when that…

Re: How to get solution solved faster in 2D Explicit Dynamics
@FernandoTorres The solver may not show you an error, you might have to go into the folder structure and look for errors in one of the files. I don't know which file or folder that is, but I have seen replies in other discussions in the Explicit Dynamics forum that say which file and folder to check.
