Incorrect results for shell model

1

Hello everyone,
I am trying to run the model of NAFEMS LE3 Benchmark as presented in the website below
http://www.caesarsystems.co.uk/NAFEMS_benchmarks/le3.html

Unfortunately, with the input files which can be found here

the results are far from being correct. I checked the same mesh and setup in different solvers and the displacement in X is very close to the target of 0.185 m in all of them apart from CCX.

Could anyone suggest what might be wrong with this?
Thank you!
