What is the best method now to solve advection equation?

Submitted by xiashengxu on

I am solving the advection equation which is hyperbolic. Some basic techniques (shown on the page  http://www.cse.illinois.edu/iem/pde/discadvc/) are either of large oscillation or numerical diffusion.

I am striving to find a method without or with little of these problems. Or is there any post correction method to use?

 

Thank you all!

I have divided the old notes on temperature into three parts:

Our feeling of hotness comes from everyday experiences. These experiences indicate that many levels of hotness exist, and that all levels of hotness can be mapped to a real variable.

Post Doc Fellow Position at The Rehabilitation Institute of Chicago

Submitted by cwisniewsk on

A full time Postdoctoral position is available immediately in the Sensory Motor Performance Program at The Rehabilitation Institute of Chicago. 

Under the general supervision of the assigned Senior Research Scientist, the Post Doc Fellow will be responsible for the development of a three-dimensional multi-scale finite element model of the human knee, and will compute the stress/strain fields in the joint soft tissues before and after common orthopaedic surgeries using three-dimensional hyper-elastic formulation.
