Actually, I really like to use central differencing, but I am facing ocillations when I am using it. Therefore, I used linearLimited(V) 1 successfully, however, there sill a...

Actually, I am not really sure about the usage of lmitedLinear 1; I spotted it in a tutorial. Basically, I tend to use schemes which are both of high order and bounded. However, as...

Replies: 42 Explanation bounding k and bounding epsilon Views: 37,384 Posted By idrama Explanation bounding k and bounding epsilon Hey Foamers, I have no idea what is bounding k and bounding epsilon supposed to mean. Can anybody explaing, please? Druing my simulation I am getting such messages with even negative values. ...
