Which software of these is better for Conjugate Heat Transfer analysis and rotating domains ?
Conjugate Heat Transfer (CHT) analysis is a type of simulation that involves the coupling of heat transfer in fluid and solid domains. Rotating domains are a special case of CHT analysis where the fluid or solid regions are rotating with respect to each other. Both PowerFlow and XFlow can handle CHT analysis and rotating domains, but they have different advantages and disadvantages.
PowerFlow uses a Cartesian lattice to discretize the fluid domain, and applies an immersed boundary method to handle complex geometries. This makes PowerFlow very efficient and robust for CHT analysis, especially for high-speed flows and large temperature gradients. However, PowerFlow requires a separate mesh for the solid domain, and the coupling between the fluid and solid domains is done through interpolation. This can introduce some errors and reduce the accuracy of the solution. Moreover, PowerFlow has some limitations in handling rotating domains, such as the need to use a sliding mesh technique or a moving reference frame¹.
XFlow uses a Lagrangian approach to discretize the fluid domain, and does not require any mesh for the fluid or solid regions. This makes XFlow very flexible and accurate for CHT analysis, especially for multiphase flows and fluid-structure interactions. XFlow can also handle rotating domains without any difficulty, as it can track the motion of the fluid and solid particles in the rotating frame of reference². However, XFlow can be more computationally expensive and memory intensive than PowerFlow, and it may require more user input and tuning to achieve a stable and converged solution.
Therefore, the choice of software for CHT analysis and rotating domains depends on the specific problem and the desired accuracy and efficiency. PowerFlow may be better for problems with simple geometries, high-speed flows, and large temperature gradients, while XFlow may be better for problems with complex geometries, multiphase flows, and fluid-structure interactions.

In which of these software I can generate FMU file ?
An FMU (Functional Mock-up Unit) file is a standard format for exchanging and co-simulating dynamic models using a combination of XML files, binaries and C code¹. According to the web search results I found, XFlow supports the generation and export of FMU files, while PowerFlow does not²³. Therefore, if you want to create an FMU file from your CFD simulation, you should use XFlow.
