Hello all,

I'm working on the tutorial problem for icoFsi solver, named "Hron Turek FSI". The icoFsiElasticNonLinUlSolidFoam gives good results for the movement of flag end. The problem is when you more delve into the solution files such as phi in each time step, you can see you have a non-zero mass flux for the moving wall of the plate into the fluid domain. However, the phi, which is relative mass flux, must be zero at wall around the fluid domain, even for moving wall.
The question is: Is it normal to have a mass flux from moving wall into the domain of the fluid?

Any comment is appreciated.
