total solution time in dynamic explicit analysis

Hello,

 I'd like to know how the computation time depends on the element number in a model (dynamic explicit analysis in Nastran). When I work with a simple model which has a rather coarse mesh the function is linear, so 10 steps with the increment 0.001 is equivalent to 100 steps with the increment 0.0001. But I don't know how this dependency will evaluate if I build a much more complex model. Maybe it will be exponential?

Thank you

hi....I have one question...it is: what is the minimum weight of a water droplet pending on the roof that it will fall down....my question is this ...shall we use both ΔP and surface tension for the solution??? plz guid me....thanks

The ANAND model in ABAQUS.

Submitted by zidane611 on

Hi, all

   I am a newer with ABAQUS. I have to simulate mechanics of a new material with ANAND model.

   I want to know whether a built-in ANAND model was in ABAQUS6.91 right now. And how to use it? I have seen in somewhere that someone said ABAQUS 6.5 had built ANAND model, but I don't find any information about ANAND model in ABAQUS6.91 I am using now.

   I hope you can tell me something about it.

   Thank you very much.
