Radial displacement despite constraint

Filip Klouda

Hello,

 

I have model in which some nodes are constrained by SPC, they should have zero displacement in radial direction, I use cylindrical coordinate system. In results I see all nodes have displacement in radial direction. It is transient analysis with moment load. I attach the file.

 

Does anybody know what is wrong?

Hi @Filip Klouda

 

Are you using the user-defined system in HyperView?

 

I see results for displacement as zero for all nodes in radial direction

Hi Prakash Pagadala,

 

I am using user-defined system. It is transient, you must go to next time steps to see the displacement. It is strange, because when I plot displacement, I see zero in plot legend, but when I use Measures tool and measure incremental distance between two diagonal nodes, it is 26 in the last time step. Also from animation I see it is growing in radial direction. See picture below.

 

Either me or HyperView is doing something wrong.

E-13 is nearly zero.
