hpc-elmerfem

Build, review, debug, and automate ElmerFEM workflows. Use when working with Elmer `.sif` solver input files, mesh directories, equation and material blocks, multiphysics coupling, boundary conditions, transient controls, or ElmerSolver execution and output issues.

HPC ElmerFEM

Treat ElmerFEM as a solver-input workflow centered on the .sif file plus a mesh directory.

Start

  1. Read references/sif-workflow-manual.md before creating or editing a .sif.
  2. Read references/block-and-equation-matrix.md when mapping simulation, body, material, equation, solver, and boundary blocks.
  3. Read references/mesh-boundary-and-output.md when working with mesh directories, body IDs, boundary IDs, and result files.
  4. Read references/cluster-execution-playbook.md when staging an ElmerFEM workflow for scheduler-backed cluster execution.
  5. Read references/error-recovery.md when ElmerSolver parsing, coupling, or solve behavior fails.

Additional References

Load these on demand:

  • references/solver-controls-and-linear-systems.md for direct versus iterative settings and nonlinear or steady tolerances
  • references/transient-and-timestep-control.md for transient simulation blocks and timestep policies
  • references/elmergrid-and-mesh-conversion.md for mesh conversion and ElmerGrid workflows
  • references/simulation-body-solver-matrix.md for block-responsibility and ID-mapping lookup tables
  • references/physics-output-matrix.md for physics-to-solver-to-output selection tables
  • references/error-pattern-dictionary.md for structured parse, ID-mapping, and solver-family failure signatures
  • references/cluster-execution-playbook.md for mesh-directory staging, launch style, and cluster-side continuation planning

Reusable Templates

Use assets/templates/ when a concrete .sif scaffold is needed, especially:

  • heat_steady.sif
  • elasticity_static.sif
  • heat_transient.sif
  • stokes_minimal.sif
  • elmerfem-solver-slurm.sh

Guardrails

  • Do not invent SIF keys outside documented Elmer syntax.
  • Do not mismatch Body, Material, Equation, and Boundary Condition IDs.
  • Do not reuse a solver block blindly across unrelated physics.
  • Do not treat mesh boundary IDs as self-explanatory; map them explicitly.

Outputs

Summarize:

  • physics family
  • mesh directory assumptions
  • core solver and equation blocks
  • body and boundary mapping
  • expected result files
