Description
TotalLagrangianSPHSystem consists of two sets of particles. One is the moving particles and the other is the fixed particles.
The latter is not integrated over time, i.e. not stored in v.
Thus, we can't apply the density calculator ContinuityDensity for the boundary model in FSI.
#369 checks that this configuration is not used for FSI.
This Issue is a reminder to fix this in cycle 0.2

Research direction
Start by tracing how TotalLagrangianSPHSystem stores moving and fixed particles, then inspect the interaction between BoundaryModelDummyParticles and ContinuityDensity. Review issue #369 and reproduce the FSI configuration; done means this combination works correctly instead of being rejected or left unsupported.
