Great video, can you do a video for randomly arranged particles?? I did this by using the rand command. but the spheres are overlapping with each other :(
Thank you for this video. Can you please do a video for randomly arranged particles within a cube, when there are 3 or 4 different types of particles randomly scattered within a rectangular Box ?
This is an informative video!!! I just see the video that uses function "meshgrid" with 3 parameters. May I ask, can I conclude that meshgird(x,y) is for 2D-coordinate, and meshgrid(x,y,z) is for 3D-coordinate? Thank you in advance :)
Does anyone know how we would get a diamond structure instead of a FCC structure? And why all of the atoms are so close together but when we list our own dimensions but make them spaced correctly in the one
That depends on your lattice constant. Your length needs to be an integer multiple of the lattice constant in that direction for you to get a nice periodic cell.
The length we give is arbitary right, it can we 7 nm, 10, 44.85 nm etc or whatever. In that case after creating the structure and cutting the length how do we still have to have PBC? simply adding lat_p/2 does not work. I am just trying tounderstand how to do this. Your code is very efficient
@@tanujgupta8381 you need to understand periodic boundary condition. Your lattice needs to be identical on opposite edges for periodicity to be maintained. That's why I said you need a multiple of lattice constant. Adjust the length values a few times and you'll see what I mean when you achieve periodicity.
Laser heating can be modeled as an ultrafast increase in temperature. And that can be achieved using the common LAMMPS thermostats such as Langevin, etc.
Take a look at the documentation here: lammps.sandia.gov/doc/fix_langevin.html I may make a video on this in near future so subscribe and turn on notifications so that you don't miss that! Thanks!
Again a me too young to understand it maybe you should make videos about expanning some physics about how things work like a how a plane flies how a gear works but great to see you again
Idk how I found this video but it's just what I need. Thank you
Also just wanna say this is really neat

big thank u!! You saved me a lot of time.
Great Explanation, can you do a video for randomly arranged particles within a cube, but not overlapped and randomly placed?? Thanks!
"Why am I using a complicated script to generate a simple structure" I ask myself everytime I plot Limacons and cry myself to sleep 😂😂
Ahaha bruhh 🤣
I always find myself asking the same question while building my systems.

Indeed. You can look at the matlab documentation of this function for more details.

Great teacher
Helped massively thank you!
Thank you so much!
Does this ensure periodic boundary condition? For some length of X I get periodic BC for other lengths I dont get it.
That depends on your lattice constant. Your length needs to be an integer multiple of the lattice constant in that direction for you to get a nice periodic cell.
@@MdShajedulHoqueThakur Well, if the length is not integer multiple of lattice contant then we dont have periodic boundaries?

smooth!
Do you have some idea of laser heating of metal in molecular dynamics?
Laser heating can be modeled as an ultrafast increase in temperature. And that can be achieved using the common LAMMPS thermostats such as Langevin, etc.
@@MdShajedulHoqueThakur Exactly you are right ... could you send a code so I will get some idea?

very nice video 👍 would like to thank u for increased brain cells
BIG BRAIN MOMENTTT 👏
what if i just need a plan cube to be plotted
Same code, just without the face centers.
Bhaiya shob joss khali tomar akta cocomelon intro lagbe :p
Ahaha yuss absolutely :v
