Description
Return scaffold void volume and complementary fractions.
Biological engineering calculations combine supplied geometry, material properties, transport and quantity bases. An ideal channel resistance, scaffold fraction or thermal time scale can be dimensionally consistent without establishing real process conditions, safe exposure or biological performance.
Return scaffold void volume and complementary fractions.
When to use this tool
Use Scaffold Porosity Solid Volume Term when checking the stated benign geometry, transport, phantom or material-basis term.
How to use the tool and how it works
- Enter bulkVolume, solidVolume. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read voidVolume, porosity, solidFraction. Use the output convention below.
Return scaffold void volume and complementary fractions. Require bulkVolume > 0 and solidVolume in [0,bulk]; void = bulk-solid, porosity = void/bulk, solidFraction = solid/bulk.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| bulkVolume | Bulk Volume | Required. Finite number; strictly above 0. |
| solidVolume | Solid Volume | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| voidVolume | Void Volume | Required. Finite number. |
| porosity | Porosity | Required. Finite number. |
| solidFraction | Solid Fraction | Required. Finite number. |

}Limitations and assumptions
- This does not establish open-pore connectivity, permeability, structural capacity or biological suitability.
- 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 verified properties, calibration and the complete applicable engineering model; assess actual laboratory/device conditions and biological suitability separately.
