[SOLVED] Constraint Tutorial scene crash

[Sen]

Hi

I am trying to run the C:\Haptics\sofa\v15.12\src\examples\Tutorials\Collision\AdvancedResponseConstraintBased.scn scene to play with constraints

runSofa crashes with this when I try to animate.
Can anyone confirm it works on their setup?

The error I get in the runSofa console is

FROM SOFA [ERR] >> [WARNING]
FROM SOFA [ERR] >> [MechanicalObject “Collision Cube”] Vector dforce(V_DERIV)does not exist
[WARNING] [MechanicalObject “Collision Cube”] Vector dforce(V_DERIV)does not exist

FROM SOFA [ERR] >> ERROR in vector<RigidCoord<3,double>>
FROM SOFA [ERR] >> 9affd750 size 0 : invalid index 0
Assertion failed: i < size, file C:\Haptics\sofa\v15.12\src\framework\sofa\helper\vector.cpp, line 47

And the stack trace is

I dont see a way to set dforce in scene files .
Since its the tutorial scene, presumably I have some setting incorrect. Any pointers on how to debug.

Correction.
Works fine if I just run
runSofa C:\Haptics\sofa\v15.12\src\examples\Tutorials\Collision\AdvancedResponseConstraintBased.scn

So the problem happens when i launch it from Modeller –> run in Sofa.

I wonder if importing the scene into Modeller corrupts it. Anyone face a similar issue?

Hi Sen,

The Modeler is known to cause this kind of issues since it has not be maintained for a long time.
Thus, we advise you to test your scenes directly using runSofa.

Cheers,
Guillaume.
