Incorrect results for shell model

Hello everyone,
I am trying to run the model of NAFEMS LE3 Benchmark as presented in the website below

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!

try to make a full models rather than quarter only, avoid symmetric boundary condition for shell element. it has been shown cause some problems as discussed in another threads.
