| t | The medium temperature at which the following characteristic values of the medium apply. |
| rho | Density of the substance at the given temperature. |
| cp | Specific heat capacity of the substance. |
| ny | Viscosity of the substance. |
External medium file
If you have entered own material values, the table can be saved and loaded as an external file using the Load ... and Save ... functions. If a file is loaded, the medium data are also saved in the project to make sure that the values are available for all participants without exchanging the medium file.
