# What are the additional CFD options to work with nTop?

## Objective:

Learn about the CFD options possible with nTop

## Solution:

There are different pathways for you to export your geometry out of nTop and run CFD. You can choose the path based on your requirements:

|                                                    | **Integration**        | **Solver Technology**   | **Best Used For**       |
| -------------------------------------------------- | ---------------------- | ----------------------- | ----------------------- |
| **Tools for Rapid Iteration / Design Exploration** |                        |                         |                         |
| **nTop Fluids**                                    | Native                 | Lattice Boltzmann (LBM) | Internal flow           |
| **SimScale**                                       | Implicit Interop       | Immersed Boundary (IBM) | Conjugate heat transfer |
| **Luminary Cloud**                                 | Implicit Interop       | RANS (GPU-based)        | External aerodynamics   |
| **Hexagon scSTREAM**                               | Implicit Interop       | Immersed Boundary (IBM) | Electronics cooling     |
| **Tools for Design Validation**                    |                        |                         |                         |
| **Ansys Fluent**                                   | Mesh-based translation | RANS (CPU/GPU)          | Any                     |
| **Siemens Simcenter Star CCM+**                    | Mesh-based translation | RANS                    | Any                     |

As of today, these are the available options. This will evolve as we add more capability to nTop Fluids and Implicit Interop.
