Transient structural: Solution unable to converge

[Ovidiu.Flori]

Hi,

It's the first time when i'm trying to do transient structural analysis and i don't have experience with it.

I'm trying to setup a Transient structural analysis of a structure ( shock impulse ) 3 strikes consecutive at 100G at a time interval between them of 0.004 s and it works for the first 2 steps ( from 0 to 100 g and back to 0 ) but when the solver is trying to converge the second strike the error occured " The solver engine was unable to converge on a solution for the nonlinear problem as constrained " .

Can someone help me with that please?

Hi

There are lots on this on the site and on internet See here (just search):

Convergence

Hope the above gives some general tips, but

as you might be in contact with Ansys customer support allready, I would suggest to proceed there as we might need to look into your model (something/model review, that can not be done here in the forum).

All the best and I hope you resolve the issue soon.

Thank you

Erik
