我穷人一枚,在版上买的复习资料,别的看的还行,但是发现没有reg的simulation题
目,大家都怎么准备的啊,是再买wiley的test bank cd做题目么,可是好贵啊,版上
有没有要share的?我下周末就考了,很怕sim这部分。

因为Becker和Wiley上的练习题都是直接给出答案的那种,不方便练习。

我是ME的PhD(4年国内+4年美国工作经验),其实更对口的工作是在automotive
industry (Detroit, MI),可是汽车行业现在朝不保夕,加之有小孩,实在不想从东北
往Detroit搬。拿到一个DC附近的Aviation Simulation Modeling Engineer的Offer,
正在犹豫这个换行值不值得。DC同类职位,像我这个背景,Salary大概在那个范围?

it is the simplest technique in molecular simulation compared to gcmc,md,

整个问题为:
dy/dx=f(y,z)
dz/dx=g(y,z)
知道y0和zL
不知道z0
能用Runge Kutta方法吗?
y方程向前走的时候,需要用到z0,而z0需要z方程倒退到最后才能知道。
如果z方程倒退的话,好像也要用到YL才行,y方程还没解哪能得到YL阿。
这个方程能simulation出来吗?具体应该怎么算呢?请大侠们帮帮忙!

Use Karhunen-Loeve expansion of w(x), to obtain an approximation:

来自主题: Computation版 - simulation of a set of stochastic ODE
For a set of stochastic ODE
dX/dt = A*X + F*e,
where e is white noise with known variance and mean
I know how to do without noise term. But with the noise term, what is the
most common way to do the simulation? Generate a bunch of random numbers first
then add them in one by one? Or a more "educated" method than this?

来自主题: Computation版 - simulation of a set of stochastic ODE

actually X is a set of variables. Here I am sovling a stochastic ODEs, not
just one.
Let me flip coin for the question: I have raw time series for a bunch of
variables. Someone said they all can be well simulated using stochastic ODEs.
So he goes ahead and use dX/dt = A*X + F*e to fit my time series. Now if I
wanna test how good such stochastic ODEs can predict future time series, which
way is the most effective way to tell?
Thanks. :-)

If you suspect a bug in the reciprocal Ewald summation, have you
verified your assumption by running a simulation with the real part
of the Ewald summation (the erfc contributions) included but the
reciprocal and correction Ewald contributions excluded and showing
that this gives conservation of the extended Hamiltonian?
