I use Fluent.

Following are the steps for an error to appear:
1. Open Fluent without Workbench.
2. Import mesh which is made with Gmsh app.
(the file format is ".unv")
3. Energy eq.: ON
4. Select "Species transport" for Species model.
5. Reactions: Volmetric ON
6. Select "CHEMKIN-CFD Solver" for chemistory solver.
7. Import CHEMKIN format mechanism
(Select three types files: "chem.inp", "thermo.dat", "tran.dat"
8. When I click the "import" button, the error(code: 127) appears.

The chemical reaction model to be used are following three mechanisms(only input file):
