hi,all.I am trying to move a face in a 3d model and i keep getting negative volume when i run the mesh motion after several steps.I used smoothing and remeshing,and the parameters are gived by refering to mesh scale info.I have reduced the time step and still it didn't work.I also changed the remeshing parameters but no go.I find the grids which are near the moving wall didn't remeshing,the grids deform until negetive volume is found.what should I do?I have troubled with this problem sevral days,i need help.The cross-section profile of the 3d model after deformation is given.
