Hi, I kind of hit a roadblock in my endeavor to optimize the cabin of my aircraft with crash and level flight case haha.. It's sort of do or die situation here so to say !! I need help in , how to combine two load steps together for minimum compliance design. Both the load cases are linear static. Both the load steps require separate sets of BCs and load. I tried doing Compliance Index and Weighted Compliance but it's giving me this error " *** ERROR # 1996 *** in the input data: All entries have zero scale." which I do not understand . I tried to define index multiple times but I am missing something and making some mistakes but I am not sure what? Any help will be highly appreciated. Thanks !
Hi, I want to create weighted compliance response for the load steps. But , when I try to create weighted compliance and click on load steps- I am getting a message - 'THERE ARE NO VALID LOAD STEPS IN THE MODEL. Background on load steps and load collector : I have 1). Pressure load , 2). Localized pressure load and , a third load collector is created with 'LOAD ' card image to combine these two loads. (snapshot 1 ) Now, I created one more localized pressure load and combined with (1) using one more load collector with 'load' image. Load steps were created for each of the loads 1, 2 , 3 and 4. Else - even if I am just creating two random loads and creating corresponding load step for them. I Still get the same message of NO VALID LOAD STEPS Can somebody tell how to sort this issue ? What can be the reason behind this problem? Looking forward to a timely response. Thank you.
