Description
Return penetration-depth step and reference discrepancy.
Soil bench and profile terms depend on geometry, reference origins, heat-capacity bases and sign conventions. A pressure, stress or strain is a limited measured/model quantity rather than a complete soil-strength, heat-transport or field-state assessment. Reference lines and physical coefficients are supplied rather than inferred.
Return penetration-depth step and reference discrepancy.
When to use this tool
Use Penetration Depth Step Gap when checking the stated soil geometry, thermal, mechanical or measurement convention.
How to use the tool and how it works
- Enter firstDepth, secondDepth, referenceStep. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read step, residual. Use the output convention below.
Return penetration-depth step and reference discrepancy. Require referenceStep >= 0; step = secondDepth-firstDepth, residual = step-referenceStep.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstDepth | First Depth | Required. Finite number. |
| secondDepth | Second Depth | Required. Finite number. |
| referenceStep | Reference Step | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| step | Step | Required. Finite number. |
| residual | Signed observed/calculated-minus-reference difference under the operation specified above. | Required. Finite number. |

}Limitations and assumptions
- Depth direction and units are supplied; actual penetration, instrument calibration and soil strength are not inferred.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use calibrated measurements and an appropriate complete soil/engineering model for material properties, field behavior or safe practical loading.
