Ms. Yanxin Feng 1 Report post Posted July 10, 2017 Hi everyone,I runed a new model in CAESES, but when I was trying to use NSGA-II to get the optimization results. The results showed a lot of extreme values. Is it because that the mesh I did in CAD part was not good enough? Did anyone also have the same problem? Share this post Link to post Share on other sites
Mr. Carsten Fuetterer 9 Report post Posted July 10, 2017 Hi Yanxin, it looks that these extrem CFD results come from a diverged solution. You can check this by going to the result of one of these designs and check if the mesh is ok or not. What application is it? best regards Carsten Share this post Link to post Share on other sites

I suppose that the mesh of fluent is created automatically in GLRankine. The meshed is imported, rather than created in CAESES. It looks like the screenshot in the attachment.I also checked the stdouterroroutput.redirect of those extreme results. It seems normal but just has several more interations.I hope you can find sth wrong from the stdouterroroutput.Thank you so much!Best regards,Yanxin Share this post Link to post Share on other sites
Mr. Carsten Fuetterer 9 Report post Posted July 11, 2017 Hi Yanxin, I can not really tell you whats going wrong. Can you identify some geometry problems for theses designs? In which format do you export the geometry from CAESES? best regardsCarsten Share this post Link to post Share on other sites

Hope this can explain your question. If not please leave me an email so I can send the case to you via email. It is not appropiate to post it in public. Hope you could understand me. Thanks!
