I am performing a welding simulation (coupled thermal-structural analysis), it's a transient analysis (50 load step). In the last load step in the structural part, I perform a re-start to change the boundary conditions of my geometry. When I try to read the results, I get the following error message for each load step prior to the last one (50): 

 *** WARNING ***                         CP =    2503.844   TIME= 22:09:32
 Cumulative iteration XX may have been solved using different model or   
 boundary condition data than currently stored.  POST1 results may be    
 erroneous unless you RESUME from a Jobname.DB file for this su-bstep.  

The calculation set is the following:

        nlgeom,on                  

        solcontrol,on              

        lnsrch,off                

        eqslv,pcg,,2              

        !eqslv,sparse,,2            

        pcgopt,5,,,,,incore         

        pred,on                    

        autots,off                 

        kbc,0                      

        nropt,full,,on             

        neqit,200                  

        cnvtol,u,1,0.02,2          

        cutcontrol,plslimit,5    

        nsubst,1,1,1               

        allsel,all

        outres,all,none

        outres,all,all

 

How can I fix this warning?

 

Best regards

Hi

I think all it says is that your .db and .rst results file are different (BC or mesh), and hence gives you the warning.

As it says use resume before restart, or when you enter POST1 to load the correct .db sub step matching the .rst file you are looking at. I hope this helps.

Also this should be of help and explain things perhaps:
