Qualitative example
The model shown in Figure 14 consists of a two-mass spring-damper system. The mass on the left is rigid and has a total mass of 1.1 Kg. The mass on the right is a sandwich of two rigid masses glued to a block made of a very soft rubber material undergoing large deformations. Figure 15 shows the Adams model while Figure 16 shows the Marc model. The Marc model is composed of 1000 solid elements.
Figure 14 Two-mass spring-damper system.
Figure 15 Adams model.
Notice the Adams model has a GFORCE at each interaction point.
Figure 16 Marc model
Also notice the Marc model has a node at the same interaction points. All nodes on the far right and far left surfaces are glued to the respective interaction node by means of RBE2 elements.
The new feature example provides a configuration script and shows all of the steps required to instrument both the Adams model and the Marc model, and run the co-simulation.
The co-simulation takes a few minutes to finish. Figure 17 shows a snapshot at time t =1.37s. The figure shows superimposed screen dumps from both Adams and Marc at the same simulation time.
If you plan to use two hosts, you need to modify the configuration script and set the correct IP address of the host running the Glue code. All the steps to run the example are the same.
