@Negative Volume, Thanks for the clarification. Your explanation helped and was similar to that provided by Ansys Ls Dyna support staff.

Hi @Negative Volume, Thanks for reaching out. In the Control_Implicit_auto, I have set IAUTO = 0 to ensure a constant time step. I have also specifi...

@francesco-curzio Thanks for your suggestions. It solved the problem! Apparently, Ls-Prepost inserts an additional row of zeros whenever you import da...

@negativevolume I have checked and my time-step (1.25e-3) is consistent with sufficient increments (100) to reach the exact termination time of 0.125....

@negativevolume I am modeling a soil-structure interaction and would prefer to avoid any non-linearity in the dynamic response (i.e. the analysis is b...

@negativevolume What happens if a local coordinate system is not defined? Does Ls-Dyna assume the forces are applied in the global coordinate system? ...

Thanks for your help. I was able to run the analysis.

@icebreakersours Thanks, I was able follow all the suggestions provided using a rigid shell element to apply the bending moment to the solid element. ...

@negativevolume how do I mesh the shell element so that all the nodes coincide with the nodes on the solid element. I have tried auto mesh without any...

@negativevolume I have modelled a pile foundation using solid elements and would like to evaluate the response of the pile when bending moment is appl...
