  1. Is the tribology simulator software a working one? when I press on ”Run” I get error of:
    ”error using waitforallfiguresclosed (line 9)”
    ”error while evaluating uicontrol callback”
    Is there an updated version of software?

  2. Just a question, this software is a freeware or not?


  3. Hello Tribonet,

    I am using Ubuntu and I haven’t been able to run this code due to it being a Windows tool (it’s in a .exe format not supported by Ubuntu). However, MATLAB is able to run on Ubuntu. Is there a chance I could get the underlying MATLAB code to implement directly using MATLAB?

    thanks in advance,

  4. Dear Dr. Aydar Akchurin,

    My name is Dzung investigating wear particles. Currently, I try to use tribosimulator to study. However, I had some problems when I simulate it. The input file is OPD file. Simulation Type: Mixed-Lubricated Simulation. Macro Geometry: Line contact. Micro Geometry: rough and use only one surface. Contact Model: Semi-Analytic Elasto-Plastic. Solid Material: keep it. Lubrication Model: full numerical. Wear Model: Von Mises Stress Based (There are only 2 theory wear in your thesis, why does tribosimulator have 3 theory?). Tribochemistry, Thermal Modle: don’t use. Contact Conditions, Contact Grid, Hydrodynamic Grid: keep it. The problem is ”Reference to non-existent file FC”.

    Best Regards,
    Quoc Dzung

  5. I am a beginner in lubrication theory. Recently I saw the Tribology Simulator package you shared on the Internet ( and it was very amazing. I am able to get the result using the input file (Inputs.mat, Simulation Type: Dry Contact Simulation) in the ZIP file. However, when I customize the parameters for analysis, it is particularly error-prone. Could you provide some input files ( .mat) about Full Film Simulation and Mixed Lubrication Simulation ? It is best to also provide the corresponding roughness file ( .csv). I would be very grateful if I could get your help.

  6. I tried to used this simulator, but I had some problem with this. E.g.: some simulation results (wear) aren’t available, the simulation does not run in many cases. I don’t understand if I have the problem or is the software not working properly / not suitable for what it was invented for? If the latter two, it should not be available because it is misleading.

  7. Hi,

    I have downloaded the surface file, but it is not uploading to tribosolver online, I also cannot get the matlab file to run either. Do you know what the issue could be?


    • Hi Sara!

      Sorry for a delayed response. There were some issues with the server, now its fixed. You can use the online tool now.

      Best regards,
