NURBS

Hi,

I am trying to use iso-geometric elements in LS-Dyna with the keyword *ELEMENT_NURBS_SHELL_PATCH. The job manager terminates without mentioning where the errors are.

Can someone help me with this? A sample .k file using the above keyword will be helpful.

Thank you!

Regards,

Hello,

Can anyone help me with some examples of XFEM implementation in LS-DYNA? Also, is XFEM in LS-DYNA currently applicable with shell elements only?

Thank you,

LS-DYNA: How to output only specific time interval of D3PLOT in explicit analysis (crash)

I am using LS-DYNA for automotive crash simulation.

I have a need to look into great detail at a specific time interval of a simulation animation.

I need to output the D3PLOT at 0.1 milisecond per plot from certain time intervial, example termination time of simulation 100 milisecond, now for some reason I want to output D3PLOT with DT=0.1milisecond during time 70 milisecond to 75milisecond only (just an arbitrarily example) and still be able to view it by directly opening the main d3plot file in post-processing software like Animator.

Explicit Dynamics with ANSYS LS-DYNA training course

Submitted by kristeen on Wed, 09/18/2013 - 08:05

This training course covers the ANSYS LS-DYNA Interface, which seamlessly links the ANSYTS traditional environment pre- and post-processing software with the LS-DYNA explicit solver to conduct highly nonlinear, transient dynamic analyses. Sequential solutions are also discussed, in which the ANSYS implicit solver is used in conjunction with the LS-DYNA explicit solver to extend the range of applications.

Rayleigh damping and numerical damping. (Ls-Dyna vs Msc.MARC)

Hi to all of you!

I have problems about dampings.

I have used Msc.MARC to simulate a Hopkinson bar experiment. We usually use a

"numerical damping" in these analysis.

As you know, MARC is a implicit FEM and it takes a lot of time to complete each

simulation.

So, I want to use Ls-Dyna, but I have the problem of damping. In Ls-dyna, we use

the Raylegh damping: there are 2 coefficients that multiply the matrix of

stifness and mass.

Is there any relation between these two kinds of dampings?
