What causes singularity in your FE model?

That FEA problem used to drive me mad It happened to me a countless number of times. I had just finished to set up my FEA model and run the analysis and I knew more or less what range of stresses I wanted to find. I was waiting for the results to confirm that… BUT…As […]

How to face a singularity error?

If you ever started to do linear static FEA Analysis, you probably encountered the following singularity error: ERROR [2007]: FACTORIZATION FAILED DUE TO A SINGULARITY AT TRANSLATION-X OF NODE 111 (RANK=5262) What is the cause of this singularity error? This error is generated when matrix decomposition cannot progress any further due to the presence of singularities. […]
