Dear All, In my problem case, I do not have any distributed load at the boundary which means no boundary Neumann boundary condition. However, I have a point load at one of the nodes (found the node and change the value) which I do not state in the KellyEstimator module and I am blind-guessing that this might be problem. Do I need to pass this information to the estimate() function, if yes, could you help me on how to do this?
