Offset-method is applied to determine inter-phase values in Euler–Lagrange/DEM model.
- class="label">•
Fluid grid is shifted in space several times and the inter-phase values are calculated.
- class="label">•
Offset-method improves the calculation accuracy up to an order of magnitude.
- class="label">•
Accuracy of offset-method depends highly on the resolution of the fluid grid.

Optimal ratio obtained between grid size and particle diameter in the range of 2 to 3.
