Thanks I will follow your instructions…but I have some problem with the visualization of some tutorial in Modeler…when I run some of them in Sofa I receive an error message: “Error running sofa,error code”.
Any idea?

my vtk file described a triangular mesh. I visualize it on SOFA following the instructions in the tutorial StepByStep / Visualization / Meshloading and rendering (2/7) ,that is:

Clear the scene to start with just a root node.
Add a MeshVTKLoader node component and rename it “loader”.
Change the filename of the object to the path name of my organ.vtk
Add a OglModel.
Save my scene file by Selecting File> Save. We will refer to this file as myTutorial.scn.
In my XML editor, open myTutorial.scn. Look for the line:
OglModel template = “ExtVec3f” name = “oglModel8”
After the property name, add src = “@ loader”.
Save the file. Re-open myTutorial.scn in the Modeler.

Now I would like to do something similar to the deformable model of the tongue for my organ…but when I edit the deformable tongue tutorial in modeler if I try to run it on SOFA I receive an error message: “Error running sofa,error code”.

Well…thank you! Now I can load the mesh of my organ.
Now I have a root whit MeshVtkloader OglModel and VisualStyle node in the Modeler tree.I can run this scene in Sofa and visualize my organ.
I would like to know how to make my organ deformable whit a spring mass model or finite element simulation.Sorry I’m a beginner and I don’t know how to create these simple steps using the Modeler.

Thank you so much … after installing QT5 now everything works perfectly

Ok, so the only way to install SOFA on Mac OS X is starting from the source code … I have followed the instructions on the site and launching bin / runSofa_d I get the following message:

what can I do ?
