When should I use them?
The most important thing I want to know is, what does it mean to use pointwise constraints with an equation of x*fsi.nX+y*fsi.nY+z*fsi.nZ? I understand that when I use a pointwise constraint of x*fsi.nX+y*fsi.nY+z*fsi.nZ, it means x*fsi.nX+y*fsi.nY+z*fsi.nZ=0. But what does this physically mean?
In other words, if I define a prescribed mesh displacement, say x=0, then I know it means that the mesh does not move in the x-direction. Similarly what does the pointwise constraint signify/represent?
I am hoping someone will answer my question.
Thanks,
Sirisha
