Hi,
I have problem using NEC ND3530A burner with various software, imgburn and
nero. I could burn some movies and data dvds and it suddenly stopped working
by giving "Could not perform end of Disc-at-once" error. I did google but
no luck, I have DMA on, and tried to burn within 4300MB and slow the burning
speed to 2.4X but no luck. I put one of the logs here and really appraciate
if someone can help.
thanks

请教一下各位高人：
我想模拟一下纳米磁性粒子在电磁场中的性质，不知道各位有没有这方面经验。
用COMSOL是不是可以做这种模拟？　会不会体系太小导致有限元失效？
多谢

FEM has nothing to do with the material/dimension.
what really matters is mathematically, what kind of the governing equation
you are dealing with.
I think you can use FEM as long as it's PDE field problem.

多谢提示了。粒子小了，应当还是麦克斯韦方程，只要我们不考虑量子效应的话。
