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
