Generative Design Always Produces Just A Huge Blob Of Material

[wallandt]

Hi, I really hope I am not doing something stupid but I have created a part which I wanted to use to try out generative design, having had little success in the past, even with the demo parts. 

On the attached drawing, I have set the loads originally at their operating load, but have now decreased the loads down to 1-5 N each. The part is currently stainless steel and the parts are 5-10mm thick. Safety factor 1. 

I would be expecting thin spindly generative design pieces but instead I get a blob, often larger than the original piece. What on earth am I doing wrong - I seem to have tried every variation in the settings I can think of. 

Many thanks

Thank you in advance.

Can you please, share the model?
