It's because there are duplicate nodes where the edges of the surfaces were. So those elements are not actually connected together. You don't see this...
I guess it depends what you mean by surface geometry. If you are talking about CAD like an .iges file, then no, PrePost does not have this functionali...
Great question! Generally, it's best to avoid this whenever possible but sometimes there is no other option. *Control_Solid has an option called ESORT...
First off, different types of elements require different element formulations (ELFORM): hexahedral elements (ELFORM=-2 to 3), tetrahedral elements (EL...
So just to clarify, LS-Dyna is suggesting a value of 0.833 which is the same as 5/6. I recommend that as well, but you will be fine using 1 in a basic...
So I opened up your file and there are quite a few issues probably causing your problem. First your *Control_termination endtim is the total time for...
Okay so I assume you've tried using the default NCPU and Memory values as well. What is your simulation? Are there any contacts? What type of contacts...
Interesting...are you running this on a personal computer? How much ram is available?
What is giving the error? Is it in the Ls-dyna manager or your computer? It may have to deal with the amount of memory available for simulation. Try m...
Ah, yeah PrePost isn't really know for it's meshing capabilities and there's not much documentation for it. Wow sorry to hear that you had to create a...
Sorry I didn't see this response before. You will need to split the geometry with a plane. So you need to fist create a plane in Surf -> Plane, pos...
Right, it will create 3D hex elements using the 2D shell elements as a starting point. The 2 lines shell function worked for me, you just have to make...
Were you able to get it to work? I'm curious as this could be a useful tool for people who don't want to pay for designated meshing software.
It's true that fully integrated isn't always the best option and can add stiffness, however less integration points does not always mean "better" resu...
