Thermal Conductivity dialog

This dialog allows you to enter thermal conductivity data for the selected material.

Thermal conductivity data

The thermal conductivity (k) of a material is the rate of heat transfer by conduction per unit length per degrees Celsius. It is essentially a measure of the rate at which a material can dissipate heat. It is measured under pressure and at a range of temperatures, or averaged across the material's melt temperature range.

The dialog shows the thermal conductivity data in tabular format, as follows.

• No. (Number) is the number of each individual material record.**
• Each row of the table shows the thermal conductivity data at a given **temperature. In many cases, the table consists of one row.
• Temperature (T) is the test temperature.
• Thermal Conductivity (k) is the thermal conductivity at the given temperature.
• The Heating/cooling rate is the rate at which the material was heated or cooled when tested. Typically this value is zero.

Note: Click Plot to display the data as a plot that shows the thermal conductivity as it varies with temperature.

Thermal Conductivity Test Information

This section of the dialog contains information about the material test such as the source, method and date of creation.

Measurement type

Option to specify if the values provided are the Bulk or Anisotropic through thickness values. From the Autodesk Moldflow 2024 release, the solver can take into account fiber orientation to determine the anisotropic thermal conductivity. It does this by taking the bulk thermal conductivity values and calculating the influence of fiber orientation. So it should only be performed on bulk thermal conductivity values. If anisotropic through thickness values have been applied here, the solver will not apply the anisotropic thermal conductivity calculation.
