I can see the symmetry bcs for u is defined as D u=1, maybe you can set it as N u=0. Regards, Wei On Tue, 2 Jul 2024 at 12:31, 🌸那慢慢🌸 <2644878715@qq.com> wrote:

Dear nektar++ users and developers,
I am using the Adaptive SFD method to calculate the flow field information when a square column experiences vortex shedding. But I have calculated many times according to the prompts in the user guide document, and the following two results are displayed:
Vectors are lineary independent
NaN found during time integration
How should I set up an XML file to ensure correct calculation? I will attach my calculation file.
I run the command ：IncNavierStokesSolver Cylinder-4.xml.gz Cylinder-4.xml
