Radioss ERROR: 402; ERROR :178; ERROR;179

Hello,
I am preparing Crash Bumper Analysis in Hypermesh 2021.2 (Radioss 2021). The problem is about spots - springs, that connect grey, yellow, green elements (scr below). 

 

The error is:
ERROR ID : 402
** ERROR IN ELEMENT PART DEFINITION
DESCRIPTION :
1 PART(S) REFERENCED BY ELEMENTS DO(ES) NOT EXIST. THIS MAY CAUSE OTHER ERROR MESSAGES IN THE MODEL
/SPRING/40 ELEMENT(S) DEFINED IN NON EXISTING PART ID 40

If i change springs Card Image to "Part", the error is:

ERROR ID : 178
** ERROR IN PART DEFINITION (PROPERTY)
DESCRIPTION :
-- PART ID: 40
-- PART TITLE: SPRING2N_comp
PROPERTY ID=0 DOES NOT EXIST
PROPERTY: 0,

ERROR ID : 179
** ERROR IN PART DEFINITION (MATERIAL)
DESCRIPTION :
-- PART ID: 40
-- PART TITLE: SPRING2N_comp
MATERIAL ID=0 DOES NOT EXIST
SUBSET : 0
VIRT. THICKN: 0.000000000000

How to define spring2 elements correctly in the latest Hypermesh / Radioss version?

Thanks in advance for any tips
Best regreds

Hi

the spring is set either with two or three nodes depending on the /PROP/TYPE selected

 

E.g. if /PROP/TYPE4 you 2 nodes and need to define mass and stiffness.

in the case of /PROP/TYPE13 , you will need 3nodes , and the 3rd node is to define the orientation of the spring section as  transversal stiffnesses, torsion and bending stiffness are present in the formulation.

 

I hope this is helpful
