Dear Mr. Johnson and MPB Users I tried a Loop to increase line defect of PCW, and study its effect of dispersion curve. But facing Error: CHECK failure on line 243 of ../../../../src/matrices/blasglue.c: non positive-definite matrix in potrf then solve_kpoint(0.219355,0,0): Solving for bands 1 to 6... and MPB Broken and will not continue any Iteration. the location of error is random, I mean some times in 5th titration and some time in other iteration this problem happened. I searched on the forum, but unfortunately I Couldn't understand solution for this error. I have to mention when I run examples or .Ctl file with few number of iteration, I will not face such a problem Any Help!
