Hello,

 I have bending radius with 5 mm and sheet metal (blank) thickness 1mm, then in the forming setup what is correspondence of the level of adaptivity.

on the basis of adaptivity theory how can we decide the level of adaptivity?

hi sumit,

 

Its a very simple rule in FEA, regardless on the bending radius you define, you need to concentrate on number of mesh defined on each fillet or critical regions in your geometry. Minimum of 5 elements should be captured in each fillet.

 

Also regarding Adaptivity, mesh your geometry with 2 element size and define the adaptivity level for 2. So that a element size of 2 will be divided twice.

 

Or you can also follow a fine mesh rule.. I.e Mesh your blank with element size same as your Blank thickness. But, Keep Adaptivity OFF to follow this procedure.
