Struggling with the Boltzmann Collision Term?

AI Thread Summary
The discussion focuses on challenges in solving the collision term of the Boltzmann equation for simulating partially ionized plasma. A splitting technique is being used for advection in phase-space, but difficulties persist with the collision term. Participants express a willingness to help if more details about the specific numerical methods are provided. Clarifications on the term "splitting" are requested to offer more targeted suggestions. Overall, the conversation emphasizes collaboration and the need for detailed problem descriptions to facilitate assistance.

Hello,

I'm working of the Boltzmann equation to simulate a partially ionized plasma, but I'm having troubles to solve the collision term. I'm using a splitting technique for the advection in the phase-space, but I'm quite stuck in the collision term. Any recommendations?

If you are still interested in this problem maybe I could help. I have spent the last few weeks working with the Boltzmann and fokker-planck collision operators. I take from your question that you are solving the collisional Boltzmann equation and are having a hard time numerically solving the collision term? Maybe with a few more details on what it is that you are doing I could provide some suggestion.

In what way do you mean "splitting"? I have some ideas but I am not positive.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
