Description
Problem
We currently treat all problems with generalized-alpha time integration. However, there are cases where we would like to solve a (quasi)static problem (e.g. G&R).
Currently, I set density = spectral radius = 0. However, @yuecheng-yu and I are unsure if that actually solves a static problem in svFSI.
Solution
- Let the user choose between different time integration schemes
- Implement a (quasi)static "time integration":
- Velocity and acceleration are always zero when evaluating the problem
- Displacements are predicted based on previous solutions
- The current solution should not depend on any previous solutions
This might be tricky since svFSI is solving for accelerations by default. @MatteoSalvador, any thoughts on this?

Research direction
No files, tests, or entry points are named. Start by locating the generalized-alpha time-integration implementation in svFSI and reviewing how accelerations, velocities, displacements, and prior solutions are handled; done means users can choose schemes and the static scheme meets all three stated evaluation and dependency requirements.
