Harmonic Analysis warnings.
 

Hey everyone. I've been doing a harmonic analysis FSI using ANSYS Workbench 15. I've been having some warnings which i am not sure how are affecting the end results of my model. I've looked through this forum and the internet but haven't got anything definite yet.

The Warnings I have are:
1)Element shape checking is currently inactive. Issue SHPP,ON or
SHPP,WARN to reactivate, if desired.
2)Material number 7 (used by element 31827 ) should normally have at
least one MP or one TB type command associated with it. Output of
energy by material may not be available.

Hope that someone would be able to clarify how important those warnings are. Sorry if I missed the response somewhere.

Best Regards,
