need help for Tutorial 3 - Laminar Flat Plate
 
3 Attachment(s)
when i come to tutorial 3:Laminar Flat Plate,i did as the tutorial guidlines,but i din't get right results.
here is the cfg file and the results.
could anyone help me?:(
ps: i must say when i set the CFL=(1.2,50,1025),then i will get NAN.

PPS:just a moment ago,i tried Tutorial 5 - Turbulent Flat Plate,but the results seems wrong also!!!

The reason for NaN maybe is the limit of CFL is too big (you set it equal to 1025).

i know that,so the CFL number in the tutorial 3 is not good,but i change it to 10,and then i get the results as the first picture in my thread(the results is not agreement with the results in the tutorial 3).
the second picture is the tutorial 5's solver error,no matter what CFL number i set ,it runs NAN.
