If you reduce the solution time you should be careful to monitor the energy balance to make sure that you do not adversely influence your results. In explicit analyses you specify a solution time and the solver advances in an incremental manner.
burningDiesel (Bioengineer) 5 Dec 13 04:47 Thank you RE: Linear Simulation taking suspiciously long in Explicit.
I feel the simulation time should be 'short' (less than 2 hours), especially since I define the material as linear.Īny suggestions would be greatly appreciated
The landing gear falls to the platform in the same way a helicopter w/ a skid landing gear would fall for a standard drop test.
So, can any of you tell my why my simulation takes so long (about 2 days)? Any suggestions on how to speed this up? The material is completely linear. Also, the mesh consists of approximately 2000 shell elements. This gear is connected to a node (this node has mass/intertia properties defined to it) via beam connecters defined in abaqus. The interaction between the landing gear and surface is defined as "surface-to-surface (explicit)". The landing gear falls onto a discrete rigid surface composed of one single element. The solver is Explicit, and the simulation is set to 5 seconds with automatic time steps. The material is Aluminum and I define this material as if it were always linear (I do not define any plasticity or nonlinear property). I have a simulation in which a skid landing gear falls to the ground. I explain the details of this simulation below. In fact, I think the simulation should take less than 2 hours but instead it takes about 2 days. In general, I want to speed up the time it takes to run my simulation.
