fea.plan — Plan a RunMat FEA study or sweep without solving.

fea.plan(study) validates and plans a .fea path, fea.Study, or fea.Sweep without executing the solver.

Syntax

plan = fea.plan(study)

Inputs

NameTypeRequiredDefaultDescription
studyAnyYes—A .fea path, fea.Study object, or fea.Sweep object.

Returns

NameTypeDescription
resultAnyFEA object or operation result.

Errors

IdentifierWhenMessage
RunMat:fea:LoadFailedA .fea document cannot be read, parsed, or resolved.fea: failed to load FEA document
RunMat:fea:InvalidInputA builtin receives an unsupported argument pattern or object type.fea: invalid input
RunMat:fea:OperationFailedA validation, planning, run, result-query, comparison, or trend operation fails.fea: operation failed
RunMat:fea:InternalAn FEA object or operation result cannot be converted to a RunMat value.fea: internal error

How fea.plan works

  • The input is a text path or typed study/sweep object; integer arrays have no input role.
  • Planning resolves model data, runs validation, selects the versioned operation sequence, and writes planning evidence before returning.
  • Plan counts, indexes, revisions, and other discrete metadata are structural integer outputs and remain exact; estimated physical or timing quantities retain their declared floating representation.
  • Planning does not intrinsically require native OCCT when supplied geometry is already loaded or uses a non-OCCT import path. A topology-bearing CAD source may require its configured geometry importer during document resolution.

Example

Plan a study

plan = fea.plan(study);

Using fea.plan with coding agents

Open a RunMat example with live inputs, then ask the agent to explain how fea.plan changes the result.

Run a small fea.plan example, explain the result, then change one input and compare the output.

FAQ

Does planning run the solver?⌄

No. It validates and records the selected operation sequence without solving.
