If Robot had a Direct Integration (The Simplest and Slowest) Solver it would become the go to for Non-Linear Time History. Non-Lin Time History Analysis requires Direct Integreation since none of the other solvers are unconditionally stable. Imagine running a 6 hour analysis only to find that the solver is computationally unstable "it has happened." I say it would be the go to because the ability to analyze on the cloud is huge for this application. A typical ASCE 41 Analysis requires a minimum of six analysis runs at around 4-12 hours apice depending on the TH and model. The current standard is Perform3d which would take up to Six Days per iteration to run the model. If this could be cut to 1day by pushing it to the cloud that would be amazing!!
