Analysis of a Transmission Model Including Contact
Using the Iterative Solver
We present another application of the powerful iterative solver in ADINA for structural solutions that can include
large deformations, plasticity and contact. In the
Our application now is the analysis of a transmission. The model is shown below, followed by the analysis statistics. Contact takes place in this problem, as shown in the plot of contact forces in the next figure.
With this level of computational performance, the ADINA iterative solver is clearly effective for many linear and nonlinear analyses.
