This is correct.

sorry my fault :oops: I should have read better the home page before posting ...

Ok, I changed FreeCAD verison to 0.19 and your code is working now, but when I choose CCX_Results and change slider value I see that the mesh is different, but the values are the same like in position zero on slider. Could you help me with this ?

This slider is just to visualize the results. A faktor of 1.0 shows the real deformation compared to the origin geometry. The results will be mulplied with the faktor. Means if the faktor is 1000 the defored geometry shows the deformation 1000 times mor than the real deformation.

Hope you got the point.

HI Bernd, I have one more question. So when I have slider value =0 then i should see my initial geometry, and when I change it to 1 it will be geometry after adding forces ?

Any value different from 1 shows your deformed geometry. If the faktor is 1, you can see the calculated deformation like in real. Means if a edge is 1 m long and your deformation is 0.1 m than the shown deformation should be around 1/10 of this edge length. If you change the slider to faktor 10, the deformation ist still 0.1 m BUT it is shown 10 times bigger, thus the deformation 0.1 m is as much as the edge length of 1 m.

Try the Calculix 3D cantilever from Start WB. There the coss section length is 1.0 m and the max. deformation 0.087 m (ca 0.1 m).

The description from @bernd don't hold for the frequency analysis.
