  I am using ANSYS 2021/R2 Student edition to simulate RC beam and received the following error message
  The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information.
  How I can solve this error
  Thank you

  Hi Also the below shows a recommended way of simulating RC structure (slide 10 shows for the Menetrey-Willam model a setting to help with convergence):
  Thank you

  I use the Menetrey-Wiliam model a setting but new error coming
  An unknown error occurred during solution.Check the Solver Output on the Solution Information object for possible causes.
  I use in Solve Process Settings Number of utilized cores 2 and on the Home tab, I untick the 'distributed' option
  but still there is error as per the attached picture
  Please help to solve the problem
  Thank you
