[FAQ]

Use FX,FY,FZ and FSUM on a path has some limitations that have been documented in ANSYS Help: “When user defined results FX, FY, FZ, FSUM, and FVECTORS (and MX, MY, MZ, MSUM, and MVECTORS) are scoped to a path, then it is possible that no contours will be displayed. The reason is that these types of forces/moments are solved only at constrained nodes. The result value at a path point is interpolated from the nodal values of the elements that contain the path point. If a path point touches an element in which some nodes have undefined reactions, then Mechanical cannot properly interpolate the nodal values for the path point. No contour color is displayed at such a path point.” This should explain this issue. A workaround is to go to worksheet under solution and create a user defined result for ENFOZ(element nodal force) scoped to the path. It may be able to provide some kind of nodal force information along the path.
