Hi Everyone, 

 

For 2D direct stability analysis of Nektar + +, when raising the NumSteps, I get different eigenvectors and I'm not sure which is correct (as shown in the figure).

 

TimeStep  = 0.004                                           TimeStep = 0.004

NumSteps = 4250                                            NumSteps = 8250

 

 

Why does NumSteps affect the results and how do I set its value?

 

Looking forward to your reply!

 

Best regards,

 

Xiangjun Shan
