Errors resuming OpenFAST from a different directory

[mayankchetan]

Bug description
When using WrVTK=3, the checkpoint stores the path to the .out or .outb file relative to the run/execution directory (where OpenFAST was run from). If the execution path is changed when generating the mode shape visualizations, OpenFAST throws the error:

FAST_RestoreForVTKModeShape_Tary:FAST_RestoreFromCheckpoint_Tary:FAST_RestoreFromCheckpoint_T:Cann
ot open file "Turbine/Case01/Turbine.out". Another program like MS Excel may
have locked it for writing.

This error is generated AFTER OpenFAST writes the mode shape viz files to currentPath + path in checkpoint file.

Use Case: Running OpenFAST linerization sweep on HPC and downloading results to process locally with ACDC.

To Reproduce

Folder structure:

Project << execution dir initially >>

Turbine

Case01 << execution directory for mode shape generation >>

vtk
Turbine.fst
Turbine_***dyn.dat
Turbine.ModeShapeVTK.chkp
....
Turbine/Case01/vtk/****.vtp << newly created when generate mode shape viz >>

Case02
....

Run.Bash

Steps to reproduce the behavior:

1. Compile current dev branch
2. Run any model with above folder structure from the Project dir, with WrVTK=3
3. Generate the .MBC and .viz file using your preferred tool (openfast-toolbox, Matlab-toolbox, ACDC)
4. Run mode shape viz using openfast -VTKLin Turbine.ModeShapeVTK.viz from within directory Case01
5. See the error above
6. new folder Turbine/Case01/vtk is generated inside Case01 with mode shape files even after the error. <>

Expected behavior

• Allow OpenFAST to resume execution form any directory OR Throw error to user when the resume directory is different from initial execution.
• Should not generate the Turbine/Case01/vtk folder and mode shape files when executed form a different directory
