  Dear everyone,
  I am currently working on a nonlinear problem of an RC slab with modeling without one support at the corner in Static Structural and having a problem with solution convergence.
  More details of my model could be found in here: https://drive.google.com/drive/folders/1bmApGI7Stz1RPUwFRXnJoZ9sLD_8b8Ak
  Could anyone help me with this problem?
  Thank you

  Hi
  For some general info and best practice see this post I wrote :
  
  https://forum.ansys.com/forums/topic/how-can-we-model-failure-in-reinforced-concrete-rc-slabs/
  Finally look at the force displacement graph to see that the structure reached maximum load that can be supported.
  There is no point going much beyond that (concrete models are not very accurate beyond failure, e.g., DP and MW concrete models).
  
  All the best
  Erik
