Error in Abaqus related to double skin steel concrete composite wall?

19 April 2021 0 8K Report

The element based surface assembly__pickedsurf18 has a mixture of 3d shell edges and other types of underlying elements. If a surface has any 3d shell edges then all of its facets must be 3d shell edges.

The master surface assembly__pickedsurf18 does not exist.

29 nodes have dof on which velocity/displacement/acceleration/base motion etc. constraints are specified simultaneously. The nodes have been identified in node set ErrNodeBCRedundantDof.

Analysis Input File Processor exited with an error.

This is the error I'm arising if anyone knows the reason pls suggest me do the work smoothly.

I have attached the model
