@samuele-libralato Try to make a surface to surface contact between the two parts so *Contact_automatic_surface_to_surface And add the options: Soft=...

@csuznxg Prepost can be finicky, especially between the different versions. So it’s smart to check quality prior to running sims.

@csuznxg It really just depends on the goal. If you add too much complexity like joints where you could just define a rotation then you may end up get...

@csuznxg weird that detaching and re-merging the nodes worked. There may have been some small elements or something going on. What program did you use...

@csuznxg Yes this is a common problem and that’s how you can solve it for sure. You could also model a rod-like rigid body that is nodally connected b...

Hi @csuznxg When you say negative volume, you are talking about prior to simulation correct? What type of element is it that you are measuring and whe...

@csuznxg Sorry I didn’t get back to you on this. That’s smart. So you just defined the translation in the plate instead of the circular part? You also...

Hi @malim-a Is the propellor rigid? You could use *Boundary_Prescribed_Motion_Rigid and apply a rotational motion to the part. You will need to define...

@macsnail This is a great find, nice job! So to clarify, you need to have a *Set_Shell or *Set_Segment defined?

@lsdynastudent Sure you can send it to contact@feassistant.com However, @csuznxg seemed more knowledgeable about this sim type in particular. But I’ll...

@lsdynastudent What is not working? Are you able to open the output ascii files in the Post tab?

Hi @showand56, Could you provide some background on what this is for and what software you have access to?

@if4ou Yeah I really don't know how to visualize different parts in Paraview. I don't think it is designed for that. Could you just use LS-Prepost? Or...

Hi @csuznxg, This is strange. I would try running a test simulation without any motion of the top impactor and see if the same thing happens. Theoret...

Hi @lsdynastudent, I know learning LS-Dyna is tough, especially when you are working with explosions (which I am not familiar with.) But I would sugg...
