OVERVIEW
I am putting together a structural model that includes materials such as steel and concrete with a elliptical kind geometry. The steel rig restrains the concrete ring from shrinking as a result stresses are developed in the concrete ring which leads to failure and cracks begin to propagate.
ERROR MESSAGE
"KEYWORD CARDS FOR STEP DEPENDENT INPUT MUST APPEAR THE FIRST*STEP CARD"
This is what appears whenever i submit my prescribed model for analysis. Please i will appreciate any ideas on how to navigate through this challenge.
