Re: [petsc-users] Question about NASM initialization

I am following up from the last inquiry. I read the source code nasm.c and it looks like sub-snes iteration is being initialized with a scatter call from the previous solution. In other words, if I use Newton's method for the local

[petsc-users] Question about NASM initialization

Hello PETSc devs, I am using SNES NASM with Newton LS on the sub-SNES. I was wondering how the sub-SNES chooses the initial guess during each NASM iteration. Is it using the previously computed solution or is it restarting from zero?
