HI Heinrich I understand the software connector part! Thank you very much! The part where the archive disappears seems to be different from the process you described. The problem I encountered (as you said is unlikely to happen), if it happens next time I will try to use screen recording and come back to you for advice! Thanks for your help!!! Best Regards YuKai

HI Heinrich Sorry for causing you trouble For example, I clicked controlDict in the Input File interface to enter and modify endtime, setting it as a modifiable parameter. I also set some parameters in snappyhexmesh. In the software connector I have to run it first to trigger CFD, is this step correct? So if I modify parameters later, do I need to do it again in the software connector? I tried to modify a parameter and then saved and closed it normally. After reopening the project, the parameters returned to the unmodified values. I'll go look for it and see if it's a problem with my computer. Thanks for your help!!! Best Regards YuKai

Hello! I would like to ask, after setting up and completing the software connection, I need to run it once to ensure that Openfoam (CFD) is triggered. Does this step need to be performed every time I modify any parameter in Openfoam? At present, if I don't execute it once in the software connection interface, all the parameters I adjusted will return to the original settings. In addition, after I archived the file, some of the originally set parameters changed back to their original state when loading the file, which troubled me very much. There were even cases where all the files were lost after loading and I had to restart the settings. I would like to ask if there is any way to solve it? Thanks for your help!!! Best Regards YuKai

HI Simon thank you for your reply I'll check my configuration settings again and set the grid size Thanks for your help!!! Best Regards YuKai

Hi! Normally, the results of using coupled openfoam to calculate resistance in CAESES optimization and pulling out the optimized shape separately for openfoam resistance simulation will be the same? (Assuming all configuration settings are the same) The resistance results currently calculated during optimization are different from the results obtained when I took the optimized model out separately and used openfoam calculations (without CAESES coupling and then performed Opemfoam simulation). But all configurations and models are the same. What might be the problem? Thanks for your help!!! Best Regards YuKai

Hello Johannes Yes, the same problem occurs when the project is not started. Could this be related to computer equipment? Thanks for your help!!! Best Regards YuKai

Hello Johannes I still can't solve it after trying the method you mentioned. Are there any other methods I can try? The current situation is still the same as in the picture. Thanks for your help!!! Best Regards YuKai

Hello! After I open my model in 3Dview, it shows that it is open but I cannot see the model. The mouse also displays information about objects Thanks for your help!!! Best Regards YuKai

Hello! How should I solve this check error so that Local Optimization in DAKOTA can be executed smoothly? check failure [multiple objectives for single objective optimization. Note: you can introduce a weighted normalized sum of the objectives.] I first used sampling in Dakota as basic optimization. I produced a total of 10 results in sampling. I wanted to perform Local Optimization on several of the results, but a check failure message occurred. How should I solve it? Thanks for your help!!! Best Regards YuKai

HI Heinrich, Thank you for your reply, I will try it. Best Regards YuKai

Hello!! How should I set constraints so that CFD will not run when the slpoe parameter is greater than 45? Let CFD only performs the parameters I want Thanks for yours help !! Best Regards YuKai

HI Heinrich Thank you so much I understand Best Regards YuKai

HI Heinrich After I tried it, I found that if I used the first method you mentioned, he would run out of sobol_02 and start running again. The second method will also run out of sobol_02 and start over. Is this correct? Best Regards YuKai

HI Heinrich Thank you so much I will try to see it right away Best Regards YuKai

Hello!! If the error occurs when the optimization and CFD are performed, the CAESES is closed, will it continue to execute the place where you can re -interrupt? For example, I use SOBOL to deform 20 projects and perform CFD computing, but the storage space is full when it runs to half, so that he cannot continue the operation. So, can I continue the operation from the interrupted place next time? Thanks for your help!!! Best Regards YuKai
