Hi everyone,

I am having trouble to model composite laminate with SC8RT element. The composite laminate is 0.1*0.1 m where the thickness is 0.01 m. I start with modeling a UD laminate with 10 plies, each ply is 0.001 m thick. I use "continuum shell" to define the layups of the laminate.

When I run the Data Check, I get the following error:

"Invalid integer value, Invalid integer value, Analysis Input File Processor exited with an error."

I tried to change element relative thickness when defining layup, and change the element number through-thickness direction when meshing, but I still get the same error. 

I would be very grateful if somebody can help me figure out what my problem is. Thanks in advance.
