      Hi,

      I am new to ansys and I am modelling a rail with springs below with two fixed ends. However, I getting the following warning message, is this a concern or how to eliminate it and how to check the created beams on solution information?

      Solver pivot error generally indicates rigid body motion. Please check if the model is constrained properly.

      to check if the model is constrained properly as in the fixed support and the spring? How come if the meshing size is smaller, I do not encounter this error?

      As for the warning msg of one or remote boundary condition has been scoped to a solid vertex, is that a concern or how to I remove it?

      Can you share the images of how springs are connected to the rails? The connection may be changing with mesh.

      Hi @akhemka
      I have done a face spilt using as a vertex as connection from a body to solid connection and below is my image of how the spring is connected with mesh image.
      If I used a lower body sizing, it will only reflect the warning as shown below. Is this a concern?

      If I increase the body size, it will show four warning and error messages.

      Appreciate your advice.

      The warning message appears when you scope the remote point to a vertex. Also, please see if the following discussion helps.
