    Hello

    I have created a 3d model in .msh format and succeeded in displaying it. I have added triangleSetTopology to my model in the code.
    The mesh is a circular disc.
    I have issues in setting the pivot point to the model to stand against gravity and not fall down .
    i have added the link to video, code and mesh:

    Cheers

    Hi @avihs98

    I think your mesh have some issue, especially on the border. In the mechanicalObject you can activate the Visualization with showIndices=”1″ and you can see that at the border of the disk, two points are always overlapping. I gues some points are not connected to the rest of the mesh.

    Look, if you use instead the indices=”3010 3050″ it works.
    I would go for a remeshing or at least analyzing the mesh connectivity.

    Thanks @Hugo

    I will try recreating the mesh. Can you please give me a sample code of how to activate
    the Visualization with showIndices=”1″ in mechanicalObject.

    Thanks

    Of course.
    Here you are:

    
<MechanicalObject  showIndices="1" showIndicesScale="0.005" />

    Hello @Hugo.

    Can you please tell me How you could find those values of indices as 3010 and 3050.

    Cheers

    Hi @avihs98

    Just change the field “indices” in the FixedConstraint.
    You will see that using these indices the Constraint works well.

    
<FixedConstraint indices="3010 3050" />

    Again let us know when you have successfully remeshed your disk.

    No Sir,

    My question was that, how could you find the indices 3010 and 3050?, Was it a trial and error method or any other specific way to find them.

    Cheers

    Hi @avihs98

    I just took two random points.

    If you want to visual the point IDs just activate the options showIndices and showIndicesScale in the associated MechanicalObject (as mentioned above).
