PVmesh Documentation

PVmesh is an open-source Python tool for generating high-fidelity, adaptive finite-element meshes for photovoltaic modules. It supports multilayer panel geometries, frame details, and mounting zones that are often difficult to mesh robustly with generic workflows.

Built on Gmsh, PVmesh automates geometry construction, partitioning, domain/boundary tagging, and export for downstream finite-element solvers.

Supported output formats include:

• .msh for ANSYS

• .bdf for COMSOL

• .vtk for FEniCS/FEniCSx

• .inp for ABAQUS

Highlights

• PVmesh automates high-fidelity finite-element mesh generation for PV modules.

• Flexible mesh controls improve element quality in multilayer structures.

• Input-list workflows support automated parametric modeling.

• Multiple mesh export formats support common FE solver pipelines.

• A GUI supports non-programmatic setup and batch generation.
