Solved Simulation Singularity Question Autodesk Community Solved: hello, i am rather new to inventor and i am busy making a simulation. in the whole assembly some high stresses occur on tiny spots. Just about everytime i run a model i create, it detects a singularity or a non positive definite. i've tried the suggestions given by the respective help topic but they never work. the only way i've found to solve the issue is to find that node and remesh around it.
Simulation With Rotation Symmetry Singularity Problem Autodesk Tips and guidance on how to overcome stress singularities, using autodesk inventor stress singularities is a major concern when analyzing results as they considerably distort results. I am trying to run a simulation on some parts i have designed, i have worked through the meshing errors with the help of another user, but have come across singularity errors when i try and solve the simulation. If you find any, the question is whether they should have some constraints on them, or if there is contact missing that would prevent the parts from moving freely. I am trying to simulate a wind turbine model in abaqus but every time i try to run the job, the numerical singularity error shows up. i simplified the model.
Is It Stress Singularity Autodesk Community If you find any, the question is whether they should have some constraints on them, or if there is contact missing that would prevent the parts from moving freely. I am trying to simulate a wind turbine model in abaqus but every time i try to run the job, the numerical singularity error shows up. i simplified the model. I am getting a non fatal singularity warning e5049 and then eventually the maximum number of bisections is reached causing the analysis to fail. i have gone through a multitude of attempts to resolve these errors. A singularity error during a static analysis indicates that the solver cannot solve the matrix of equations. there are 3 main reasons why that occurs are as follows. The image "simulation remeshed " shows that some of the elements are hidden; that's why the parts look like a jumbled mesh. you need to show all of the elements, either by "results options > view > element visibility > show all", or by right clicking on the part > "visibility" until the checkmark is solid. I'm working on a thermal stress simulation with a relatively simple 3 piece assembly. i've run a straight up static stress simulation and everything seems happy, but when i clone the static stress simulation and try and add a thermal stress, everything gets really unhappy.
