Please enter your recommended mesh protocol parameters; their limiting values and your justifications therefore in the below table. You may choose to 10 relevant parameters; and may assume that all meshing is 2D; hence no need to list element type as “shell” or “2D”. An example has been added below.

Parameter	Limiting Value (LV)	Unit	All elements X of a mesh should be	Justification
Mesh size	2.0	mm		The minimum mesh size has been defined due to argument A and B…
