Time increment in Dynamic Analysis
Time increment in Dynamic Analysis
(OP)
Hi,
I'm a new user of Abaqus, I'm making some dynamic analysis with Abaqus-Explicit in an adaptive domain with ALE technique, I have two Eulerian boundary regions with material inflowing and outflowing.
My question regards the choice of the time increment for integration in this kind of analysis. Is it possible that if I don't input manually the maximum time increment (I leave blank the space after the line *Dynamic), so I leave Abaqus to change it during analysis, I obtain a different result from the case when I input it manually choosing a lower value (to respect the condition of stability discussed in the manual)? I specify that I don't use mass scaling.
Hope you can help.

RE: Time increment in Dynamic Analysis
If it does turn out that you are getting a bad estimate on the time increment for that particular application, I suspect that it's something Simulia would want to hear about.
