#8 Singular matrix in bullet

[noesis-support]

Hello,

I'm running the bullet_AKM example and playing with the velocity.
for low/high value (<630 or >760), I have problem of singularity.
in the range 650-750, some speeds are working, some other not, with the same issue.

I'm in DOS, if I run the execution with std output/error redirection, I can't catch the java error message.

java.lang.RuntimeException: Matrix is singular.
at Jama.LUDecomposition.solve(LUDecomposition.java:319)
at Jama.Matrix.solve(Matrix.java:1316)
at Jama.Matrix.inverse(Matrix.java:758)
at run.elements.Solid_Iso_4.calculateStrain(Solid_Iso_4.java:410)
at run.Worker.run(Worker.java:109)
at java.lang.Thread.run(Unknown Source)

thanks,
Max

Other issue, in case of error, the code is not exiting which is a problem for me as I'm running a sweeping and I would like the other design points to be computed.
