Dear @Lauren ,

We have updated the Creating visualizations: Van der Waals visual model tutorial in our Developer Guide.

You can also check out the code samples corresponding to this tutorial here: https://github.com/1A-OneAngstrom/SAMSON-Developer-Tutorials/tree/master/VanDerWaals. The code samples contain more optimized code and some additional functionality.

Alternatively, you can do this without the Brenner interaction model but with the built-in minimization which uses the Universal Force Field (UFF) and the Add editor (shortcut: A) (it's Carbon by default).

First, you will need to modify SAMSON preferences (Ctrl+K):
-1- For the Add editor, disable the "Adjust hydrogens ..." option.

-2- For the Minimization, disable the "Warn me when hydrogens appear to be missing" warning to prevent it from poping-up on each new bond connection.

Then you can apply the minimization: Home >Simulate > Minimize. Start connecting atoms in the nanotube and the graphene sheet using the Add editor (A) - to create a bond simply connect two atoms with this editor.

Dear Stephane,

Yes, we have atoms. The 0.8.0 solution will be the best long-term, as we are dealing with large systems and FPS drop a lot when translating or rotating, but for now I will check the ParticlePositionChanged event.

Thanks!!

Hi,

I think I found the problem. Some initialization functions in the constructor of my class were overriding the unserialization. I tried to make a quick fix but when I do static casts in the unserialize function, SAMSON is crashing, so I will modify my constructor and check, it will take a bit though.

Thanks for your help!

I think it should be possible, it will be just an additional line in the launcher script. If we will be shipping Python Scripting with the Python environment, I think we might ship the environment with a bare SAMSON installation so that to use SAMSON Elements, that depend on this environment, the user won't need to install the Python Scripting Element.

oh you're right there is a 100 coefficient, it's giving me the coordinate in pm. Didn't think about that.
thank you very much.

Dear Stephane,

Thanks for the quick reply. I will add the position in three attributes for now. Looking forward to 0.8.0!

Perfect thanks.

This is already quite helpful, thank you!
I will try and see if displayLineSweptSpheres solves the issue.
I will post the solution when I've found it!
Cheers,
Haichao

Thank you!
I will try it with this.

Yes, I meant SBStructuralGroup :)

Thank you! Using the GetClass and GetElementUUID methods is enough for my purposes :)

Thanks, this solves my problem!

Awesome !

Thank you guys, you rock !
