LSR is on a distinguished road
I have a .def file but I want to change some options in the solver setup. Is it possible to edit it in the .def file or do I have to setup the solver again?
I don't have the .cfx file, so cant really just edit it and write a new .def file. I don't have the project as well. I just have .msh and .def files.

You can open a .def file in Pre. No props.

I use CFX preferably stand alone through the CFX-Launcher. There start CFX-Pre, and open the def, change the settings and save a new .def-file. You can run and postprocess the files also through the launcher.

Since CFX-Pre eats .def-files, .cfx-files are obsolete. Therefore I never save the case in Pre as a .cfx file. As a result, I only have .def-files and .res-files

The use of .cfx files, and .def files depends on your approach to projects.

The .cfx files keeps the history of meshes imported for a project. The .def file contains a snapshot of a model, and any extra information is removed at writing.

For example, you start assembling a turbomachine with multiple blade rows, cavities, etc. For some reason, you need to cut out a few parts to reduce the model. You do not need to delete the meshes, just remove them from the physics appropriately (replace with Boundary conditions, etc), Write the definition file, and proceed.

You can then, either move to the next model. But you still have all the pieces in the project.
