Does RBE2 & RBE3 elements work in Modal Analysis ?

I am performing a modal analysis of my sheet metal structure and I have used rbe3 and rbe2 elements to connect two sheet metal part mesh.

But, it showing error as saying 'massless body found'.

I want to ask that in modal analysis rigid body work or not?

Rbe3 and Rbe2 should work for all types of analysis supported in optiStruct.Can you try running analysis using MECHCHEK control card.If still gets error then please share the .out file?

Thanks for reply,

Now I am performing Modal Frequency Response Analysis, As a Input I have the Load exported from MSC Adams which are the force values w.r.t time.

That I have inputed in TABLED1 but how I could create the Force Load Collector as it need Magnitude to create as I have varying load what to enter in magnitude section?
