Advances in computational fluid mechanics have provided the basis for further insight into the dynamics of multiphase flows. Currently there are two approaches for the numerical calculation of multiphase flows: the Euler-Lagrange approach and the Euler-Euler approach
Since the given approach makes use of the Eulerian multiphase model framework, all its limitations are adopted:
- The turbulence models: LES and DES turbulence models are not available.
- The combustion models: PDF Transport model, Premixed, Non-premixed and partially premixed combustion models are not available.
- The solidification and melting models are not available.
- The Wet Steam model is not available.
- The real gas model (pressure-based and density-based) is not available.
- The density-based solver and models dependent on it are not available.
- Parallel DPM with the shared memory option is disabled.

The available boundary conditions, include the following:
The trajectory calculations are terminated and the fate of the particle is recorded as “trapped”. In the case of evaporating droplets, their entire mass instantaneously passes into the vapor phase and enters the cell adjacent to the boundary. In the case of combusting particles, the remaining volatile mass is passed into the vapor phase.
