[petsc-users] snes_type aspin error

[Xiangdong]

Hello everyone,

I am trying different snes_type in petsc. The newtonls and nasm all works
well. However, when I switched to aspin, I got the error like "No support
for this operation for this object type" "Mat type shell". I am using the
dmda 3d in petsc 3.6.3. The full error messages are below.

Any hint for me to fix this? Thanks.

Best,
Xiangdong
