Do you know what the problem could be?

I am sorry. I was busy. Tomorrow i will check.

Hoping someone will help you fix it soon

Hi @marvin1991 Did you provide any CID for CBUSH elements? If not can you keep it zero by card editing the elements and check if this helps.

With CID set to zero

<?xml version="1.0" encoding="UTF-8"?>

But your result is not making sense or? You have the highest displacement at the constrainsts. But the force is in the middle, between the springs. And even inthe middle the displacment is 1,9*10^-9 in the girst example. Thats nearly 0 ..

Yes that is because of the I made the CBUSH rigid just to check if this is valid. 

Without CID solver gave a random displacement and with CID set to zero it is giving expected results. 

it is recommended that another CID be selected to define the element x-axis.

okay thanks.

But when i increase the force and lower the K1 factor the displacement is still nearly 0 ..but why?

Can you tell me how to define the elemet x-axis? I have never done that before. Maybe you can send me a little example?

Thanks for helping!! /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

Hi Marvin,

I did not notice the K1 factor and load change. I will check this. 

You can create a local system and set the local system to elements. 

@marvin1991

This is with a local system and apply stiffness in right direction

<?xml version="1.0" encoding="UTF-8"?>

Awesomme! That looks good /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

Is it possible to send me that model?

Sure.
