NAN error during PARDISO

[Usman2]

Hi, I am using Pardiso to solve a member with 75,592 DOF. However, after the "Back substitution and iterative refinement" step, one of the variables gets assigned NAN value.
For another case with decreased DOF= 50010, there is no error such as NAN. 

I was wondering that what is the actual reason for this NAN error after "Back substitution and iterative refinement" step (75,4592 case). Any kind of the suggestion will be highly appreciable. Thank you!
