build spring element with force-displacement curves
Altair Employeedear all
I build a spring element with CBUSH element, define the force-displacement table with PBUSHT. But when I run the analysis, there was an error come out.
ERROR:
*** See next message about line 91 from file:
C:/Users/A044045/Desktop/rubber/rubber.fem
'PBUSH 1'
*** ERROR # 1000 *** in the input data:
Incorrect data in field # 3.
And I define the CBUSH and PBUSHT cards as follows. How could I correct the error? Thanks!
CBUSH 2 1 2 1
PBUSH 1
PBUSHT 1 KN 2 1 2

Altair EmployeeThank you very much!
you mean I have to write like the following?
PBUSH 1 K0.0 0.0 0.0 0.0 0.0 0.0
PBUSHT 1 KN 2 1 2
Does that mean when use PBUSHT card, the K values in PBUSH will not effective?
Altair EmployeeFor Nonlinear analysis KN is the type and other K values will be ignored.
Altair EmployeeThank you very much!
Hi,
Provide the K value in the PBUSH card.
The K, B, GE, and M fields for PBUSHT are associated with the same entries on the PBUSH entry
