Using PiecewiseLinear interpolated function in phase-field kernel #16286

|
Dear I would like to call Fermi-Dirac function in phase-field kernel We have the Fermi-Dirac function in csv file so we built the function as below: [Functions] but still not clear how to call it in kernel. Could you give me any comment on this? Thank you in advance. |

Hi Kunok, Just to make sure we're on the same page, you're wanting to use the Fermi-Dirac distribution function as shown below, correct? https://www.doitpoms.ac.uk/tlplib/semiconductors/fermi.php If this is correct, I would suggest it's easier to code the analytical form of the distribution function into your kernel rather than reading in the function from a csv file, since the analytical form is pretty simple. |
