When you make an axisymmetric analysis, you can chose two way to have the output result : in 2D or in 3D. The way to have the result change between the two settings. For example I juste make a simple analysis on a 10 mm diameter cylinder (20 mm lenght) . I applied a 0.1mm displacement in Y direction.
First i solve the reaction force with a simple analytic methode :
Then i make an equivalent model in Prepomax :
Now you have to choice to have you Element field output :
And here you have the two settings solved :
On the 2D methode the reaction force is given for all the cyclinder surface.
On the 3D methode the reaction force is given for a 2 degree portion of the total surface of the cylinder .
So think about that when you change your output !
