Describe the bug
I modelled a balcony with burnable objects.
Objects start to burn at an ignition temperature. After the fuel is exhausted the object burns away.
Numerical instability and segmentation errors appear after about 220s.
This happens when the objects are modelled through all meshes.
When you apply a hole at the boundary of a mesh, so that the burnable objects don't go through the meshes the numerical instablity and segmentation errors don't appear.
The balconies burn as they should.
To Reproduce
Steps to reproduce the behavior:
Take the model "BurnAway-BA0016" and run it until around 250s --> error should occur
Take the model "BurnAway-BA0020" and run it until 3600. --> nor error occurs and objects burn away completely
Expected behavior
I expect the balcony to burn away completely without errors even though objects are modelled through many meshes.
