Hello

I am starting to write a simple code with level set method by constant external speed.

but I do not know, what boundary condition shuold I use?

thanks

Simple interpolation --> Constant interpolation or linear interpolation. See Fedkiw's papers.

Which Fedkiw's paper does explain these boundary conditions?

How can I use simple or constant interpolation for

boundary conditions of level set equation?

what about periodic or extrapolating boundary condition?

thanks.

I red this paper, but I donot know, what boundary condition can I use for edges of my computational grids? this paper has used ghost fluid method for zero level set funtion, not for edges of computational grids. what can I do?

thanks
