Buckling for Cross Section Optimization through Karamba

Optimization of parametric truss

Hi! I have constructed a truss and want to optimize the placing of the diagonals for minimum mass. The problem is that I cannot find a way to limit Galapagos so that I don’t get too high deformations. I have put in a C# script, that adds 1000000kg if the solution is not within the limit of deformation. Galapagos still doesn’t want to throw away the solutions with too high deformations, and forms rectangles instead of triangles. [bilde] Does anyone have any tips on how to get Galapagos on the…

Buckling design in Karamba works correctly if you define buckling lengths within members correctly.
