Holger Vogt 0a087809d6 If both node names are the same, just print them once in the error message. 2023-11-08 13:12:06 +01:00
Holger Vogt a6d5ce8ea6 Some KLU warnings are useless for the normal user, as she or he 
does not have any means to further analyze or repair the issue:
Warning: KLU ReFactor failed. Factoring again...
Warning (ReFactor Complex): KLU Matrix is SINGULAR
    Numerical Rank: %d\n
    Singular Node: %d\n
So print these messages only in debug mode.

Francesco Lannutti 710341bbfd Fixed KLU returns values so that NIiter can Factor again, if the matrix is numerically singular from the refactorization 
Fixed the NIiter code to perform a factorization without reloading the matrix

Holger Vogt 8e175f1e77 Replace obscure warning "singular matrix: check nodes mymode1 and mynode1" by 
"singular matrix: check node mynode1", if both node names are equal.
