Whatever file i try to load into ovito it says format not supported, or atom style cant be detected or no. of columns is not expected. I keep getting an error. Can someone please help?
Thanks for watching! That is an interesting question actually. I have not tried to do that kind of a simulation, but I can think of a way it might be possible. Perhaps by creating a different temperature in different regions across a material, and then tracking the temperature evolution over time. Of course, it would be interesting to see if the results lined up with what we observe experimentally at the macroscale. I will try to work on this idea!
Thank you very much for creating this and other 3 Ovito tutorials. They are very helpful. You may consider creating a playlist containing the 4 tutorials because TH-cam did not autoplay your other Ovito tutorials when I was watching a one. Thanks again.
Thanks for watching! At the moment, I don't have any dump files available for download. However, most of the ones that I show are pretty easy to generate yourself, using some of my other tutorials. I will look into uploading some of them onto my github repository though!
Thanks for watching! To my knowledge, unfortunately no. Now, you can calculate the orientation using the Polyhedral Template Matching modifier - it will give you an orientation quaternion that you could use to get the direction of a crystallographic plane or direction, but it would take some work. Good luck!
You could model some (limited) types of fluid flow, yes. You can model fluids at the atom scale, but modeling the boundary conditions that are typically imposed might be a bit more difficult. And, if you are dealing with boundaries, you will almost certainly not be able to model a system big enough to get out of the boundary layer region - but that doesn't mean you can't have a useful simulation. What kind of fluid flow problem are you thinking of?
Love your videos! I'd like to see some more in-depth Ovito tutorials about all he different modifiers. And also more LAMMPS tutorials about mechanics of materials
Thanks for watching! Stay tuned, I am working on another Ovito tutorial on modifiers right now. Probably I could do quite a few videos just on the large number of modifiers Ovito provides.
Hey Can you help me out with something? I am using LIGGGHTS and in it I am using meshes imported from a CAD file. However, I cant figure out a way to show these meshes in my OVITO visualization which I performed using dump files as you said. Do you know how I can do that. It says so on their website that we can include VTK files but idk how to do that...
Thanks for watching! That is a good idea - I will try to include a more elaborate description of the slice command in a future video on OVITO. Certainly, Ovito has enough capabilities I could make many videos on it!
If you want to generate atom positions, you probably want to check out my videos that use Python to generate atom positions. Then, you can just change the parameters so that you create a 3x3x1 super crystal of whatever structure you want to use. Alternatively, if it is a simple structure, you can use built in LAMMPS commands to do the same thing.
Thank you for the video! Do you know how to adjust the force arrows at 8:17?

May i have a question, can you tell me how to make a hole in a metal, like lead particel.
your tutorial videos are awesome. They are the best. Please make more and more.
Thank you! I am glad you have been enjoying them. I definitely am planning on making many more. I won't go months in between new videos this time!!
Nice video. I belive the audio is a bit low(?)
The videos are very interested, can you upload video how to calculate the lattice thermal conductivity of two dimensional materials using lammps

Great tutorial, I just want to know where can I download your dump files?

Thanks for this video. I want to know is there any mean to identify a crystallographic plane or direction using ovito?

Hello Mate, I wonder if I could modelling fluid flow using Lammps is that possible?

@@Jere5120 Thanks. I have an idea and want to make a model perhaps could safe many lives, I could tell you in private if you want to help out.
@@mustafakhalil007 If you are willing to tell me, I would be interested to hear! My channel email is: encodeventor@gmail.com

VTK mesh files can be imported just like a lammps dump file. However, I don't know about LIGGHTS outputs. Sorry!
Interesting and helpfull video. Thank you very much. Hope some thing coming about Wigner-Seitz defect analysis.
Thank you for making a nice video on Ovito. Can you please show the use of slice-command in more elaborated version.

You can send for me your email
These are not the basics.
I suppose it depends on what you are trying to accomplish. What features of Ovito do you use frequently?
thank you, I need a video about how to install ovito.
