Cosmos: Static with large displacement... what method is Cosmos using?

When doing a static analysis, the large displacement flagpopped up. I then ran the analysis using the iterative technique.What analytical method is Cosmos using to do this? I read thatnonlinear studies let you choose whether to use Newton-Raphson ormodified NR. I saw no such choice when doing a static analysis, sowhat method is being employed here?SolidworksSimulation
