Has anyone ever simulate a Sparse Double Dense or honeycomb structure? seems that Solidworks underestimate these part's stiffness for my case 300 or 500 percent smaller than actual deformation. the calculation was realatively quick, but I guess Solidworks took some shortcut instead of using a lot of memory. Is there anyway to improve the accuracy? I used the smallest mesh size already.
If you use only solid elenments , you can use h-adaptive or p-adaptive methods
