paraFoam can't open STL file
 
1 Attachment(s)
Hello,

I have an annoying problem. I can't open STL file which is in constant/triSurface folder. STL file is working properly. So I think my error is about installation.

I clicked console view:

Code:

I checked the lines related with errors. They are:

Code:

    {
    vtkErrorMacro("STLReader: error while reading file " <<
      this->FileName << " at line " << lineCount << ": " << e.what());
    return false;
    }

2)

Code:

  // If the algorithm failed report it now.
  if(!result)

                  << "(" << this->Algorithm

                  << *request);
    }

  return result;

Quick question: Do you have the same problem if you run this command:
Code:

paraview $FOAM_TUTORIALS/immersedBoundary/cylBumpInterIbFoam/constant/triSurface/ibCylinder.stl
It will start ParaView and open one of the STL files from foam-extend 4.0.

Thank you very much for reply.

I run and opened it. There is no problem. I can see STL cylinder. BTW after closing ParaView, I received this on the terminal. I think it is not important because I can open an STL file at all:

Code:

Inconsistency detected by ld.so: dl-close.c: 811: _dl_close: Assertion `map->l_init_called' failed!
After that I tried to open my STL again, but I get which is working on other laptop(openSUSE 42.1, foam-extend 3.2). I received same error:

I will also attach my STL to next post because I can't attach this one.

Thank you very much Bruno, for this and for all of your effort on openFoam, foam-extend.

Sincerely

Did you use the same Paraview version on your Laptop? I recall there was a Paraview version with an STL reader bug.

Here I attached STL file that gives me error which does not supposed to do so.
It is in text file due to the restriction of uploading it in STL extension. So you can simply change its extension to .STL from .TXT.

Hello and thank you for the reply,

The working version is 4.3.1 on openSUSE 42.1.
This error I'm dealing with is 4.4.0 on ubuntu 16.04.

Sincerely,
Emre

Greetings to all!

@Emre: Sorry for taking so long to get back to you on this. Anton is right, ParaView 4.4.0 has a bug when it comes to loading STL files, as reported here: https://bugs.openfoam.org/view.php?id=1887

You will have to either have to:
  • rebuild ParaView 4.4.0 in foam-extend to use the bug fix reported there;
  • or install another version of OpenFOAM that has this fixed and switch between terminal tabs, with different loaded OpenFOAM/foam-extend environments, as explained here: http://openfoamwiki.net/index.php/In...with_the_Shell
  • or use surfaceConvert to convert the STL to another format, e.g.:
    Code:

    surfaceConvert IB_block.stl IB_block.obj

Best regards,
Bruno
