PointSupport Rotation mismatch value [SOLVED]

Help FEM-Design

Hi there :smiley:

I have a question in reagrds to FEM Design and the support’s rigidity for rotation.

I have attempted to model a point support, assigning a rotational stiffness of 7e5 in the X component:

When I deconstruct the support I get the following:

And reading the .struxml file I have the following:

However, when looking at the point support in FEM Design, I get the following:

Is there a reason for this difference? Am I missing something, or is there some kind of scaling that I’m not aware of? Has anyone else encountered this?

Ehi @AndreiM

It seems to be a mismatch between units :slight_smile:

FEM-Design API has the input as kN/rad while your FEM-Design GUI is set as kNm/°

Hi @MarcoPelle

Ah, I totally missed that :face_with_open_eyes_and_hand_over_mouth: , so that solves the ‘‘issue’’ for me.

Thank you again :smiley:

To be fair, I also had the same issue a long time ago. It is a difficult one to spot! Well done in checking the outcome :slight_smile:
