Querying the cylindrical system


I have tried to simulate an cylindrical model by using cylindrical system. The initial mesh is good. The run was killed automatically due to unbelievable large deformation as soon as it started to run. However, by using the rectangular system, the run was well.
Can you help me?

Can you share your input file?

Please find the inp model at https://www.fatbear.site/file/CY01.inp

There are some cards not available in CCX, check everyone against the documentation and remove it.

Thank you for your suggestion.

I checked the ccx_2.17.pdf and found some simple stuff related to the cylindrical coordination definition. I also tried a lot ways to update my model but not succeeded.
So can you share some detailed example? such as input file?

Did you check the *ELEMENT section, in your input file every element is defined in two lines, I donĀ“t know if this is allowed.
