  1. Step 1:

    open "tutorial_fem_piston.catpart"
    select the "partbody"
    click "apply material"
    choose "steel" on your material library and click "apply material"

  2. Step 2:

    go to start -> analysis & simulation -> generative structural analysis
    choose "static analysis"

  3. Step 3:

    create a "smooth virtual part"
    choose the generated surface of the piston hole for "supports"

  4. Step 4:

    create a "clamp"
    choose the "smooth virtual part" for supports

  5. Step 5:

    create a "temperature field"
    choose the piston for "supports"
    set temperature to 1 Kdeg (!)
    (temperature will be multiplicated with "Koeff" in .xlsx-file)
    activate "data mapping" and select the temperature.xlsx-file

    you can activate "display bounding box" to see your temperature field

  6. Step 6:

    doubleclick on "environment"
    set initial temperature to 395Kdeg

  7. Step 7:

    doubleclick on "OCTREE Tetrahedron Mesh"
    set size to 4mm
    set absolute sag to 1mm
    be sure element type is "parabolic"

  8. Step 8:

    compute your analysis

  9. Step 9:

    click "von mises stress" to show the stress in the piston
    set display style to "shading with material"
    click "animate" to se an animation

  10. Step 10:

    thats it
