DOE EVALUATE ERROR FILE NOT FOUND

Hi guys,

i encountered some problems with my optimization in evaluate step in DOE 1. I run it for two models, one for compliance optimization and one for mass optimization. There are two separate folders and files do exist in folder. I don't understand what is the problem because the files are present. Hwsolver says that there is no problem and design is feasible. Any ideas?
