Hi all,
I am running a simulation of a column subjected to a blast load using references from research papers, utilizing the MM-ALE method. However, I kept encountering the issue of the console stuck on flush i/o buffers and the time step kept becoming smaller. I tried changing my mesh size but the problem persisted. I believe the problem may be with my time step size but I am not too sure. I hope you can offer some advice to this issue. Thank you.
I would do an element quality check to make sure that you don’t have any really small elements somewhere in your model. Really small element edge length can really kill your time step and may be causing this issue.
Hi, thanks for the suggestion. I will certainly conduct an element check on my model. However, I hoped I may have found the issue in my k. file, which was my tracer setting that was set wrongly. So I decided to remove my tracer and run my simulation. So far, I haven't ran into the same issue yet so, fingers crossed.
Okay great! What do you mean by tracer? And did removing solve all of your issues?
The tracer setting under DATABASE. I wanted to study the velocity at certain points on my model. It did resolved this issue for one of my model. However, another one of model started to encounter the same issue again despite having removing the tracer setting. So, I haven't fully figured out the solution yet.
