CBUSH Element Error

mecjos

I add CBUSH element with attached PBUSH property and I get the error below.. How to add bushing element in a static analysis properly?

 

 *** ERROR #  99 ***
 CBUSH element 123782 references incompatible PBUSH.
 K2/M2/B2, K3/M3/B3, K5/M5/B5, and K6/M6/B6 on PBUSH must be zero for
 CBUSH with no G0, CID, and blank X1, X2, and X3.

 

Thank you.

Hi,

 

I think you have not defined a CID for the CBUSH, am I right?

If that is the case, basically you have to define the reference system of the CBUSH, in order for the solver to be able to understand which direction your Ks stiffnesses refer to.

You have to select the element, press 'edit', click on the 'CID' field and select the reference system for which x = direction of K1, y = direction of K2, z = direction of K3, when you are done simply click 'return'.

Let me know if it's not clear and if it worked.

I selected local coordinate system while creating cbush element in springs panel oriantation selection.. isn't it same thing?

Hmmm, I don't think so because from your error message it really looks like you don't have a CID assigned to your CBUSH.

Anyway, you can simply check the CBUSH (Card Edit --> click on CBUSH --> edit) and if no CID is assigned just do it.
