The relaxation using RelaxationStepLevelSetCorrectionInner produces weird particle distribution

RelaxationStepInner doesn't have this problem:

There might be a bug in the 3d level-set shape of this beam

@WeiyiVirtonomy yes. It seems like. @Nafug22 could you have check on the implementation? Thanks.

@WeiyiVirtonomy Could you make small test case for multi-resolution relaxation? Thanks,
