multiple thickness shells

Hi,

how can you create mid surface shell pairs in a part that has 2 different thicknesses?

Re: multiple thickness shells

Hi,

You need to use 'variable' in the shell pair definition

As there can be no common mid-surface you need to define where the mid-surface is. Note 'select placement surface'. This is an approximation and actual mid-surfaces will be moved so that they align. This will change the stiffness of the structure.

The process works in a similar way if your plates are a single part or an assy of two plates.

When you mesh, switch off 'display shells with zero thickness' and you will see what the numerical model will be ...

Regards

Hi,

I have the same problem but in CREO Parametric. Is there a possibility to solve it?
