Small equation solver pivot term encountered at UY DOF of node 2. ANSYS automatically constrained this DOF. Check for an insufficiently constrained model.
14.05.2020 · Please check for an insufficiently constrained model. The above message clearly indicates that the model is under-constrained and needs appropriate boundary conditions and / or contact definitions. Typically, I would create a named selection for the offending node (856 in this case) and identify its location in the mesh.
If a run ends in an error and the summary or log file informs you that your model is insufficiently constrained for analysis, you should examine your model ...
Well, an insufficient constraint model means when you apply the load the assembly has some free body motion. We generally mention it as rigid body motion.
When I run the model in Ansys I got the following error: Check for insufficiently constrained model. I tried to cut the model to make it smaller, and analyzed the model like this. I fixed all points in the x and z directions. The lowest of elements are all fixed in x, y, and z. This didn't work. I then cut the model to one element. It worked.
I want to analyze this model that is stressed and deformed. I fixed the lowest of points in the x, y, and z directions, and I pulled top of points upward (y direction). …
