Benchmarking CalculiX

Hello !
I’m willing to bench CalculiX performances on some platforms but I lack representative test cases.
Can I find somewhere datasets for static analysis that are open and large enough to challenge solvers behind?
Thanks !

hi,

actually it’s quite simple using CalculiX CGX, as in my previous large test case of solver type selections. i just create simple square plate (extruded) and mesh it based on edge division which can be fully controlled to highest density as desired.

apply some boundaries support and loads, due to self weight, mass or modal analysis are simple enough.

best,

below is example input file to generate model and calculation, you can try to observe about edge division and element type (line number 8&9)

model generates file (*.fbd)

pnt p1 0 0 0
pnt p2 100 0 0
line l1 p1 p2 8
seta lg1 l1
swep lg1 fg1 tra 0 100 0 8
seta sg1 A001
swep sg1 bg1 tra 0 0 10 2
div all mult 2
elty all he20
mesh all
send all abq
seta support A003 A004 A005 A006
comp support do
send support abq spc 123
