In my work, I am required to perform FEA on really long parts and assemblies.say 100 feet hollow square sections with cross section width 50 inches.And the plate thickness would be 1 inch.so they are really long and thin parts.
Solid meshing is considered.
so my question is there any good rule of thumb to get right mesh size.How many elements would be good across thickness of the plate?
In the above example of cross section if I get min of 3 brick elements thick, the no. of elements would be enormosly large which my comp cannot deal.
Or use plate elements.
