Good Evening, I have completed a topology optimisation and I am happy with results but now I want to to re-run the analysis. I open ossmooth, load the model and results, use "keep smooth layer around" and remesh using a "mixed" mesh type. I then go to run the analysis (-optskip) and I get an error message regarding compliance. I don't understand what's causing this as the loads and constraints are all attached to the non design space. Is it a mesh issue? *** WARNING # 312 In static load case 1 the compliance is negative or large 3.974381E+11 Optimization/buckling analysis cannot be performed due to possible rigid body mode *** WARNING # 312 In static load case 2 the compliance is negative or large 1.253294E+12 Optimization/buckling analysis cannot be performed due to possible rigid body mode Thanks in advance for any help, this forum is an excellent resource and has got me this far. I just need a little help with this last step. Kind Regards, Mike FRONT LOWER LEFT MODEL 2127.out FRONT LOWER LEFT MODEL 2127.hm FRONT LOWER LEFT MODEL 2127.fem
