The TDW I installed is the latest version 1.11.23. There should be nothing wrong with the tdw_physics I installed. The system I use is Windows 11.

I guess the problem may be related to TDW. There is no FluidTypes class in the latest version of TDW library.
The code "from tdw.flex_data.fluid_type import FluidType" can call the FluidType class of the new version of TDW, but its usage method is different from the previous FluidTypes. Can you help...
