No "Elementary entities" not enabled on mine

    I just saw your video. But why is the "Elementary entities" not enabled on mine? I'm using the cloud version

    It is better to answer this type of questions within Prof. Yu's research group at

    The "Elementary entities" was disabled to avoid potential issues for SG generation. For the cloud version, it is mainly used for a demonstration purpose and you can use "Common SG" for a variety of SGs. If you want to perform beam analysis, you can directly edit gmsh input file via "Edit file".

    I was following these two videos and as you said, I couldn't see the Elementary Entities option. Are there any alternatives methods to perform the macro-mechanical analysis?

    Yes I am doing a Beam Analysis. Please how do I edit in Gsmh?

    Thank you

    Click "Edit file". Assuming the beam length is 100 mm. Add the following lines to the file. Save and close the file, then following the rest steps in the videos.

    Point(1) = {0, 0, 0, 1.0};

    Point(2) = {100, 0, 0, 1.0};

    Line(1) = {1, 2};

    Thank you so much for your insightful help.


    Please what does the "1.0" represent for points 1 and 2?

    You can consider "1.0" is a mesh size. Basically, a small value gives you a dense mesh.
