Third order MUSCL Scheme
hey guys,
I am currently writing my Bachelor thesis using fluent. I am using the third order MUSCL Scheme which obtains, just like QUICK and stated in the name of the Scheme, a third order accuracy.
So I took a look into the Handbook to see how this thing is working. But instead of understanding it, I just got realy confused.
The third order MUSCL Scheme works by blending a central differencing and a second-order upwind scheme. Both of those schemes are second order accurate, so how does the whole things goes third order?
(CD: Central differential; SOU: second order upwind)
Hope anyone can Help me. I am new to this forum and hope i didnt make any large mistakes.
I am using Ansys Fluent 18.1 and got my information form the Handbook (theory guide - Solver theory - Spatial discretization)
Regards
an mechanical engineer
