    How to make bases pinned?

    Hi, I currently have a script of a two bay two storey frame, which has fixed bases, but now i would like to make them all pinned bases. The way i go about it is to change the D,28,all to D,28,ux and D,28,uy, is this correct?? Also when i run the analysis i get that the solution has not...

    Solution non convergent

    Hi, I am currentyl trying to run a non linear analysis of a two bay single storey which has been pin based, i have previously successfully run a similar script but with fixed bases. But, on the pin based approach I am getting non convergence in my solution and I can't figure out why. I have...

    Monitoring Variables and Result in Monte Carlo Analysis

    Hi, I would like to know if it is possible to at the end of a monte carlo analysis to look at a file or a results sheet anywhere in ansys that will show for EACH permuation the probabilistic design variables that were used. Thanks

    Ansys Extract Time (Load Factor)

    Hi, I am currently trying to run a non linear analysis with a monte carlo analysis, which i am confident is working as it should. But, I am missing a single random output variable in my monte carlo analysis. If someone could please help me with respect to the commands that i should use, to...

    Ansys results extraction in probaility analysis

    Dear Drej, Thank you for your helpful advice, but I still remain unclear with how I can get the time (load Step) to be extracted like a random output variable (like DMAX), how is this done? The reason I would like to do this is so that i can assess the general load factor at which a particular...

    Ansys results extraction in probaility analysis

    Hi, I am currently running a nonlinear analysis on a steel frame and then doing a probability design (monte carlo analysis). But I am having trouble with the information i am extracting, as it is incorrect. I have set up in the attached script a section that is meant to pick out the maximum...

    Excessive Rotz at node, why?

    hi, I am conducting a non-linear analysis of a 3 bay frame with an initial sway, which is modeled as perfectly plastic perfectly elastic. the aim is to find the maximum carrying capacity of the frame. when i run the analysis the error comes up saying that there rotz at node 76 has exceeded the...

    Non-linear Analysis giving Erroneous Results

    hi, I am currently running a non linear analysis with an initial sway, of a three bay steel frame. i am trying to find the ultimate carrying capacity of the frame. the results that i am getting from ansys are strange as it is shown in the attached file. the load factor only increases to 1.2...

    Non-linear Solution not Converging

    Thanks, but the frame i am modelling is from a research paper, and all the parameters applied to the script have been determined. so i am still trying solve why my solution will not converge. So is there anything else that i can do?

    Non-linear Solution not Converging

    hi, I am currently trying to conduct a non linear analysis of a 2d 3 bay steel frame which is loaded with a udl along the top of the beam and two point loads at the end of the beams. The aim is to test the ultimate load capacity of the frame. The solution uses the arc length method and runs...
