an error in RC beam modelled in Ansys workbench 19.2

      hello All,


      Hello All  
      I am using workbench 19.2 to model an RC beam with steel bars and stri. The concrete is modelled using solid 65 (command), and for the steel I used bilinear Isotropic hardening. How would I solve the following error coming during solving " There is at least 1 small equation solver pivot term (e.g., at the ROTY degree of freedom of node 120).  for checking for an insufficiently constrained model, I tried by containing the rotation of steel by adding fix rotation, am I right? I also fix the displacement of the middle line of the supports. but it is still not working. I also like to understand how we can add the load as steps on the bearing plates please?
      I am trying to model an RC beam as training to learn how to model RC beam with fibres included. I could not find any training relating to including using fibres with concrete on ansys, can anyone help me in this please?
       
      Thanks
