Remeshing Issue (also occurred when Tissue set to False)

Description

During handling of the above exception, another exception occurred:

Reproduction

import pyvista as pv
from svv.domain.domain import Domain
from svv.tree.tree import Tree

mesh = pv.read('sample_baffle_extrude.stl').triangulate()
baffle = Domain(mesh)
baffle.create()
baffle.solve()
baffle.build()

t = Tree()
t.set_domain(baffle)
t.set_root()
t.n_add(10)

from svv.simulation.simulation import Simulation

sim = Simulation(t)
sim.build_meshes(fluid=True,tissue=False,boundary_layer=False)
sim.extract_faces()

Expected behavior

Adequate remeshing -> generate appropriate vtp/vtu files

Additional context

No response

Code of Conduct

• I agree to follow this project's Code of Conduct and Contributing Guidelines

Reproduce the failure with the provided PyVista, Domain, Tree, and Simulation example, then trace the call from Simulation.build_meshes through tree/export/export_solid.py to utils/remeshing/remesh.py. Inspect the mmgs_O3.exe invocation and its non-zero exit status, and compare the generated mesh artifacts with the expected VTP/VTU output.
