Let's Write a DPD Simulation from Scratch in C! (Part 4)
มุมมอง 90ปีที่แล้ว
In part 4 of this video series, we look at the data generated by simulating polymer solutions, polymer melts, and a binary mixture of immiscible fluids and compare the results to classical polymer physics theories. The results from the code are in excellent quantitative agreement with those theories, implying the code works well. Full source code is available on GitHub: www.github.com/mjahore/T...
Let's Write a DPD Simulation from Scratch in C! (Part 3)
มุมมอง 143ปีที่แล้ว
In part 3 of this video series, we put the final touches on our code by completing the implementation of the cell list function, adding the velocity-Verlet function to advance our simulation in time, and write two functions to calculate the value of temperature and momentum for the system. We end the video by running a quick simulation and comparing the value of the radius of gyration to result...
Let's Write a DPD Simulation from Scratch in C! (Part 2)
มุมมอง 176ปีที่แล้ว
In the second video of this series, we first correct three minor mistakes that were made in the first video. We then introduce the concept of a cell list and implement it in the code along with the harmonic force. We end with calculating the root mean-squared radius of gyration of our polymers.

Let's Write a DPD Simulation from Scratch in C! (Part 1)
มุมมอง 411ปีที่แล้ว
In this video series, we write a dissipative particle dynamics (DPD) simulation for a polymer solution from scratch using C. We discuss the fundamental concepts in DPD, how to create an initial configuration, and how to calculate forces and advance the simulation in time.

Thank you, Professor, for sharing this series. I’m currently pursuing my PhD in energy-conservative dissipative particle dynamics (DPD) with suspended particles, and these videos have truly helped me gain a deeper understanding of the code.
It's nice that after I graduated from cwru and went to phd somewhere else, and I can still meet some professors I took classes before on ytb
Great
Thank you Dr. Hore.
Hi Michael! Thank you for the amazing video! I just wanted to point out that in wr = 1.0/dr - 1.0; it should be wr = 1.0- dr;. Keep up the great work!
@@mubarakalkorbi9463 Thanks very much! What’s actually being computed is wr/dr in the code. The reason for doing this is for efficiency. Since all of the forces need to be projected along unit vectors in the x, y, and z directions… if we divide wr/dr we can save ourselves two operations since we will not need to divide dx/dr, dy/dr, and dz/dr to calculate those unit vectors (i.e., we do it once in wr and just multiply by the dx, dy, and dz we already computed to determine whether dr < rc).
those 352 lectures are definitely valuable! Thank you for uploading!
Thank you so much sir
great video. Wish I had found it earlier. Very helpful explanation.
Why excluded volume is equal to zero if we have a system of identical chains without a solvent?
Dear sir if i have a drug and polymer and need to predict stability according to ratio of mixing let say drug is 20% and polymer is 80% so how to predict if its a good blend miscible and what is the chai value and delta Fmix
many thanks sir its really genius how to simplify the FH theory
Thank you so much for this great video. I have sent you an email about this topic. It would be great if could check this email.
Thanks for sharing your knowledge and giving this nice lecture. All the best.
Hello sir, I am a PhD student trying to calculate brush height from trajectory data i got from my lammps simulation. Thank you for this video but I am not quite clear as to how you measured the cumm' length 'b'. Please can you clarify? I am writing a code for the calculation. Thank you.
b is the Kuhn length, so the distance between 2 neighbouring segments (monomers)
