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
