No results are displayed in the core walls table

[pta_simon]

I have a Robot model and ran the calculation with no problems but the core walls results table has no results shown.

All values for the forces and moments are N/A.

Is there any reason for this happening?

I have attached a dropbox link to model below.

Thanks.

Are you sure you sent us correct model?
I can see many distorted elements and bunch of instabilities type 1

I sent the correct model.

The type 1 instabilities related to torsional rotations (RZ) so I took the view that they were not critical to the overall results but I did not see any warnings regarding any distorded elements?

Are they out of plane panels? There should not be any instances of this due to the methodology we use to build the models, although we have noticed Robot has a tendancy to modify the geometry when meshing which could be the cause?

Whatever.
Decision is yours. I will check model.
BTW please install the latest SP for RSA 2014

Lack of results for stories on which core walls do not exist.

Example:

CW 1 ("Core wall left hand side") starts from Story 3 so lack of results for Stories 1 and 2

I have solved the problem relating to the core wall results and fixed the instability nodes.

You mentioned in one of your earlier posts about distorted elelments. I have no error message warning me of this. I have updated to the latest service patch and still no warnings. Could you plesae clarify where there are distorted elements in the model? Thanks.
