We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi,


To apply the above water modeling approach in ansys WB (mechanical) I ave used remote attached point masses to model (M0) and a 1m3 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.


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 handdel 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. Could anyone give a hand please?!!


 



 Note: the springs and the point masses are attached to the structure using x, y, z location with the remote attachment method and their locations may not match nodes locations.
