Hi, all. Section 5.5 of the documentation implies that the material temperature is used to determine appropriate cross-sections. Is it used for anything else, like changing the density of the nuclides within a cell or alter the mesh to replicate thermal expansion, please? Thanks.
Hi mjf
Welcome to the commity
You can certainly change the density of the cell to be a more suitable density for the temperature that the material is at. OpenMC doesn’t know the density of the material at specific temperatures so you would have to set the cell to the new density yourself.
The same with the cell volume, openmc has no knowledge of how the cell expands with temperature so you would have to adjust the dimensions accordingly.
