BWB error

[Дмитрий Тарабащук]

Dear SUAVE team,

I learn how to use BWB tutorial. I have Installed all necessary programs:

1) OpenVSP

2)GMSH

3)SU2

But when I run tutorial I always face with errors. I know that this problem was raised earlier in discussion, but for me it is still unclear:

At first I faced with this error:

    f = open(filename)
FileNotFoundError: [Errno 2] No such file or directory: 'base.key'

So, okey after I launched BWB.py I got following files:

And decided rename base_premesh_NASCART.key to base.key

After that I faced with next error:

With geometry in OpenVSP everything good

Thank you in advance

Hi,

That final error is something to do with SUAVE not finding SU2. SU2_Home is not in your environment.

Hi Emilio,

Thank you for advice, but I ran SU2 tutorial and SU2 works well as standalone program.

I think the issue in base.key file. 

I am not sure that trick with renaming file from base_premesh_NASCART.key to base.key will work, because as it shown in error above no mesh were created : ''Error   : Mesh generation error summary''.

1)Do you have any other assumption how it can be solved?

And  could you show/attach how should looks like file" base.key"? 

Thank you for your efforts and help!

kind regards,

Dmitrii

Hey,

Yeah the mesh is not correctly made. Hence why no .key exists. One thing to try would be to go back to the version of OpenVSP the tutorials was tested on, that version is 3.26.1. Let me know how that one works.

Hi,

I am also seeing the same error. Were you able to resolve the issue?

Please let me know!

Thank you!!
