I modified my BC such that on the left and right side of the interface the BC are constant value instead of Neumann(zero flux). This solves the problem but still the code has convergence problem:
I even tried field split with the following order:
the block size is 9. the first block is the fields related to for PF equation, the second split block is the velocities in x and y direction and the third block is pressure.

-pc_type fieldsplit
-pc_fieldsplit_block_size 9
-pc_fieldsplit_0_fields 0,1   (two fields related to for the Phasefield model)
-pc_fieldsplit_1_fields 2,3  (velocity in x and y direction)
-pc_fieldsplit_2_fields 4 (pressure)
-fieldsplit_1_pc_fieldsplit_block_size 2
-fieldsplit_1_fieldsplit_0_pc_type ml (based on https://lists.mcs.anl.gov/pipermail/petsc-users/2015-February/024191.html)
-fieldsplit_1_fieldsplit_1_pc_type ml (based on https://lists.mcs.anl.gov/pipermail/petsc-users/2015-February/024191.html)
-fieldsplit_0_pc_type ilu (based on previous solutions of phase-field equations)
-fieldsplit_2_pc_type ilu

I guess changing the BCs the main reason that at first few steps the code does not fail. And as time increases, true resid norm increases such that at a finite time step (~30) it reaches 1e7 and the code results non-accurate velocity calculations. Can this also be resulted by forward/backward discritization?
Best,
Sepideh

   Singular systems come up in solving PDEs almost always due to issues related to boundary conditions. For example all Neumann (natural) boundary conditions can produce singular systems. Direct factorizations generically will eventually hit a zero pivot in such cases and there is no universally acceptable approaches for what to do at that point to recover. If you think your operator is singular you should start by using MatSetNullSpace(), it won't "cure" the problem but is the tool we use to manage null spaces in operators.

Even setting pc_type to LU does not solve the problem.

I guess the problem is that in mass conservation I used forward discretization for u (velocity in x) and for the moment in x , I used forward discretization for p (pressure) to ensure non-zero terms on the diagonal of matrix. I tried to run it with valgrind but it did not output anything.

Does anyone have suggestions on how to solve this issue?
Best,
Sepideh
