Can this tool export an FMU that supports restart ？

I need a fmu that supports restart, can this tool export a fmu that supports resart and if so how should I do it?

Can you provide steps to reproduce the problem?

I am using FMU in conjunction with fluent to do some research in CFD. In MATLAB/Simulink :

1. FMIKit.initialize()
2. select solver: fixed-step(0.001)
3. sysetm target file : grtfmi.tlc
4. built a FMU model The model is shown in Figure 1 Figure 1

In ANSYS\Fluent: The ANSYS\Fluent is shown in Figure 2 Figure 2 1.run the script like

/file/set-tui-version "21.2"
(cx-gui-do cx-activate-item "MenuBar*ReadSubMenu*xianxing")
(cx-gui-do cx-activate-item "MenuBar*ImportSubMenu*FMU ...")
(cx-gui-do cx-activate-item "Import FMU File*Table1*Frame1(FMU Input File)*PushButton2(Import)")
(cx-gui-do cx-set-file-dialog-entries "Select File" '( "Deal.fmu") "FMU Files (*.fmu )")

When I import the fmu model, it gives a warning that the model does not support restart If the FMU does not support restart, when the CFD needs to be restarted after an interruption, it needs to reinitialise the solution and run the calculation from scratch. In fact, CFD is a very time consuming task and it would be very costly to re-initialize after every interruption, so I needed FMU support for restarting

I assume "reset" refers to the FMI capability flag canGetAndSetFMUstate that is currently not supported.

@zzlonggg, can you give b8db9443a5bf779467cf386002e457ed480aa082 a try? It adds an experimental implementation of the get/set FMU state functions.
