I apologize that it took so long to respond Jean-Paul, as some things came up that kept me away from working on this. I was going through the code and attempted to integrate it within Step-44 as appropriate. I appreciate your willingness to share it with me, but I have some questions concerning

Dear James, I've got some snippets of code that I'll post below to show you how this can be done within the framework of step-44. The basic concept that I implemented is as follows: - The nonlinear solver is called by some function who's job it is to solve for a single timestep. Collective

[deal.II] Adaptive Time Increment Algorithm

2020-10-13 Thread James Gorman
deal.ii users, I'm learning deal.ii with the goal of using it to non-linear solid mechanics problems. In many of these problems (such as Step-44), a time step is used to move a calculation from the initial condition to the final loaded state. Step-44 uses a uniform time-step, but there are ins
