Complex instance will not run when a real instance exists

[sseraj]

Description

Complex ADflow will not run properly when a real instance exists at the same time.

Steps to reproduce issue

Here is a MWE:

from baseclasses import AeroProblem
from adflow import ADFLOW, ADFLOW_C

aeroOptions = {
    "gridfile": "../../input_files/naca0012_rans-L2.cgns",
    "MGCycle": "sg",
}
ap = AeroProblem(
    name="mdo_tutorial",
    alpha=1.8,
    mach=0.80,
    P=20000.0,
    T=220.0,
    areaRef=45.5,
    chordRef=3.25,
    beta=0.0,
    R=287.87,
    xRef=0.0,
    yRef=0.0,
    zRef=0.0,
)

# Create solvers
CFDSolver_real = ADFLOW(options=aeroOptions)
CFDSolver_complex = ADFLOW_C(options=aeroOptions)

# Try to use run the complex solver
CFDSolver_complex(ap)

Current behavior

Running the example above will result in errors like the following:

[0]PETSC ERROR: PetscTrFreeDefault() called from VecDestroy_MPI() line 21 in packages/petsc-3.15.1/src/vec/vec/impls/mpi/pdvec.c
[0]PETSC ERROR: Block [id=1190(92160)] at address 0x5636dfd7cf30 is corrupted (probably write past end of array)

[0]PETSC ERROR: See https://www.mcs.anl.gov/petsc/documentation/faq.html for trouble shooting.
[0]PETSC ERROR: Petsc Release Version 3.15.1, Jun 17, 2021 

Expected behavior

The solver should run properly.

Alternatively, you may not see the PETSc error but the output will still look something like this:
