Subject: Meshing Problem - Mr. Metrisin

Dear Metrisin,

Thank you for your suggestion. I have never approached the problem with shell model because i thought the shell would not be the right option. I have a quick questions to ask you. Could you please answer me? (i have not done a shell model before)

1. Can a shell be used as a 3D model or should i go for a 2D to deal with Shell?. My model needed a 3D analysis because the deformation in all three axes based on cyclic thermal loading.

Thank you for doing this.
