CalculiX single node stagnation problem

HI @djmeee , the earlier tagged post provides a solution in this part which basically is to remove the stagnant unused node manually from the CalculiX mesh file. This is probably not the ideal solution and it is good that you found another solution of downgrading form CalculiX 2.16 to 2.15. Does your case also work for v2.16 normal version? Perhaps then only the Multi-thread version is the problem.
