Hello,
I am a bit new with ANSYS, and I am having some difficulties. I am modeling Reinforced Concrete, and I'm having some troubles getting the model to converge at the cracking load. I am trying to validate ANSYS with a simply supported reinforced concrete beam under third point loading. I have modeled the concrete with the Solid65 element and the reinforcement with the Link8 element. My elements are relatively small, with approximately 3000 elements for the quarter model. I set the convergence criteria tolerances to 0.5% for forces and 5% for displacements. I also decreased my load step so it is applying less than a pound when trying to get past the initial cracking of the beam. The only way I was able to get the model to converge was to remove the force convergence criterion, but I'm afraid by doing that, I am going to get erroneous results. Any suggestions or reference materials would be greatly appreciated.
Thanks
