Radius of curvature warning

[transall]

Hello,

I have a problem wiht shell93 element. I tried to mesh a straight tube made of area with this element but I have a radius of curvature warning because of the shell thickness. I understand the warning (see Anys help), I don't know how to mesh a tube using 2D element like shell. Have you some ideas?

Thank you for your help,

Best Regards,

Hello,

I suppose the radius of the tube is small in relation to the thickness of the shell. In this case I would also try a volume mesh instead of shell. Then compare the results.

Thank you for your help, I made it with small tube with same OD and thickness and the accuracy is worth with shell compared to the analityc solution
