I am running a 2 way FSI in transient structural and fluent and had a simple question that I have not been able to find the answer to. I have run my simulation with the same time step size twice.The first time, in the table where I input my load in transient structural, I only input a few values and let the program impose ramp functions between the values I set. The second time, I input a load value for every single timestep in my simulation. The results I got in each simulation where drastically different. Why is this the case? Why doesn't the simulation treat the ramping functions the same way as tabular inputs for each timestep? I'd like to increase the timestep by a factor of 10, but I do not want to sacrifice the accuracy of my model because I cannot input load values for all 1000 timesteps.

Hi Peter, I am not sure whats going on since I am able to see the images in the posts on different computers. Can someone else confirm this?
Also, I tried to save these images separately and tried to do what you suggested but that doesn't work either. I've reached out to the ADMIN, but if you feel my posts don't make sense without these images please feel free to delete them. FYI, I am unable to attach anything to a post as well.

I was able to resolve the issue. Thanks for your help! It was a problem with the way I was inputting values into the table.
