I normally wouldn't recommend prepost for meshing, however, I believe it should be able to handle geometric shapes like this. I've never done this, bu...

Glad I could help. Yeah I’m actually making a few videos right now and I’ll add one on ELFORMS too. Feel free to ask any other questions, just make a ...

Great question! So first off, using the defaults in LS-DYNA is usually an okay place to start, in this case, it is element formulations (ELFORM) 2. Th...

If you are making an object from scratch and want a thickness of 1.2 mm then you don't need to subtract it from the size since you can set nloc=0 wher...

Shape meager is going to mesh a shape from scratch, not from an iges file like you mentioned wanting to do. And you said you wanted to create a hexago...

In the section card there is a parameter NLOC, which sets the thickness direction. 0 is both directions, so 0.6mm in and out. This is the preferred me...

Yep, that's right.

Even if you mesh it with a double layer of 2D elements, you can delete all but either the inner or outer layer and then offset that layer half the dis...

Okay nice! I do not know any specific place but a google search will probably be sufficient enough. There are many types of aluminum as well.

Also, are you testing stability of this composite material in an isolated impact test? Is that the instability that you showed? It could purely be a m...

I'm not sure what is going on there to be honest. Try removing the *Implicit General card and see if it still happens. You can also try drastically in...

Yeah I wouldn’t use 3D elements for the spokes if you main goal is to provide pretension. You can use *Element_Discrete which is a 1D element that you...

So I’m not very familiar with modeling composites but I did gather together some materials that may help you here: I’m not sure of the exact applicat...

Try searching for “100 small” in both the d3hsp and message file. I’m unable you look at your gap file currently

In the D3hsp you should see a section labeled “100 smallest timestep” this lists the elemenents with the smallest timesteps in the model. So I’d find ...
