Hi,

To apply the below water modeling approach in ansys WB (mechanical) I have used remote attached point masses to model (M0) and a 1 m^3 solid box ( I had added it to the model in design modeler) connected to the structure with 2 longitudinal springs as shown in the images below.

Note: I have divided M0 into to point masses and attached one point mass to the left wall and the other to the right wall.

when I tried to solve the model this warning "Two or more remote boundary conditions are sharing a common face, edge, or vertex. This behavior can cause solver overconstraint and is not recommended, please check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window."was appear then the solution stopped with this error "At least one contact pair or remote load has no elements in it. This may be due to mesh based defeaturing of the geometry. You may select the offending object via RMB on this warning in the Messages window.".

To handle the error I turned the mesh defeaturing option to "no" and tried to solve again, but I get the same warning and the same error. I also edited the pinball region of the mass point from all the face to 0.05 meters and the pinball region of the longitudinal spring to .2 meters instead of all the face which means that each face have a pinball region of the mass point ans a pinball region of the spring and there is no contact between the 2 region.
I have also splited each wall into two face at a height half-way between H0 and H1 , but I have got the same erorr. Then in another trial I have used remote points using the "promote to remote point" option for each point mass and each end of the longitudinal springs, but I have faced the same error again!!

Could anyone give a hand please?!!
