recordValidityResult

Information

1. Purpose of model

Record returned by the validity analysis function ValidityAnalysis. It contains one status per criterion and the key figures on which the status is based.

2. Level of detail, physical effects considered, and physical insight

(Purely technical component without physical modeling.)

3. Limits of validity

- Status values: 0 = criterion fulfilled, 1 = warning, 2 = criterion violated.

- The key figures are pre-simulation estimates; see ValidityAnalysis for their definitions and limits.

5. Nomenclature

	statusDarcy, statusLTE, statusNRGF, statusBuoyancy	status of the criteria on Darcy's law, local thermal equilibrium, natural regional groundwater flow and buoyancy switch (0 fulfilled, 1 warning, 2 violated) [-]
	statusOverall	maximum of all status values [-]
	R_th	thermal radius of the stored volume [m]
	d_grain	grain diameter used for the criteria on Darcy's law and local thermal equilibrium [m]

(no equations)

7. Remarks for Usage

Returned by ValidityAnalysis; the definitions of all key figures are given in the documentation of ValidityAnalysis. Bind the result to a parameter record, e.g. parameter Records.ValidityResult validity = Function.ValidityAnalysis(...), to access the values in a model.

8. Validation

(no validation or testing necessary)
