Hi there, I am trying to use NASM to solve a nonlinear problem. In my FormFunctionLocal, I need to call DMDAVecGetArray(da, myvec, z). For the "-da_overlap 0" case, the code works fine.
For the "-da_overlap 1" case, when I use the vector "myvec" created by DMCreateLocalVector, it works fine. But if I use the vector "myvec" created by DMCreateGlobalVector, I got the error messages: ----------------------- [6]Arguments are incompatible [6]PETSC ERROR: Vector local size 597870 is not compatible with DMDA local sizes 619528 664392 ---------------------- And when I switch to "-da_overlap 2", both of the global and local version of "mrvec" got error messages: ---------------------------------- [10]PETSC ERROR: Arguments are incompatible [10]PETSC ERROR: Vector local size 589680 is not compatible with DMDA local sizes 633144 678680 [3]PETSC ERROR: Arguments are incompatible [3]PETSC ERROR: Vector local size 619528 is not compatible with DMDA local sizes 650256 696540 ----------------------------------- Can any one tell me how to use DMDAVecGetArray in FormFunctionLocal for NASM? Thanks. Best regards, Rongliang
