H Jamie, there is only one solver but with different levels
of access. The LD option in a Static study uses the same LD solver
as a Nonlinear study. The only difference is that the Nonlinear
solution gives you the response curve from min to max whereas the
Static study only gives you the final, max, response.
You should expect to see the same results. For more on this,
check out the COSMOS Companion Unit #110 notes on Geometric
Quick question about large displacments calculation in linear
vs non-linear. When using a large displacment calculation on linear
model with linear material and boundry conditions, can you expect
the same results from the non-linear solver? Will they both
calculate the same stiffness and displacments? I'm not having any
issues with this, I'm just currious about the diffirent ways that
two solvers work so that I might make better judgments on which to
use in the future.
