please use *DATABASE_NODFOR & *DATABASE_HISTORY_NODE_SET ( here SET should contain the interested / query nodes at required location )

yes i had tried , but i'm not getting a meaning full result . The wave propagation is not coming proper.

@john : There are multiple ways to simulate composite impact , using shell and solid elements. the link shared by @negative_volume is good starti...

which LS-Dyna Ball and Block Tutorial have you followed , can you share the link ,

Eroding contact will give better results . Also sometimes , if your mesh is coarse , these kind of behavior arises. Try changing the contact algorithm...

please check the following : -storage space -Model is going severe hourglass -out of range node / high deformation -Licence availability

Also you can use tied contact using segment created from the element face.

your boundary conditions might not be correct . Also check on the contact card parameters USE *BOUNDARY_PRESCRIBED_MOTION .

@yoshimori3456 : Here , the error is specific on *MAT_72 . i had look into the file you had shared . the material data is not complete. That's the r...

@negativevolume : Thanks for the reply . . . Appreciate it I was not able to resolve the issue with the version we had . Also the wear analysis m...

1) Check for duplicates 2) Check for free rigids or other elements 3) Check all contacts again 4)check material properties 5) sometimes part g...

@mr_lazlo : there are two methods to impart prestress in lsdyna : 1. Control dynamic relaxtion 2. Interface springback to get dynain. It depen...

hi , just by changing the units , there should be no change in the contact behaviour. check for Master and Slave definition. Also try to use MOR...

hi LuBo, An equation of state (EOS) is equivalent a fluid model. Specifically, an EOS is a fluid model that takes a molar composition (z) and predic...
