I am having problem if my right hand side is all zero. For all zero B the solver stuck in solution phase for inifite time and niether it exit from solution phase nor it gives error. Does PARDISO works with all zero B? Is this known problem in PARDISO or do I have to set some parameters to aviod this?<DIV></DIV><DIV>Thank you</DIV> Fri, 09 Mar 2012 11:10:49 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Pardiso-behaviour-having-right-hand-side-quot-B-quot-all-zero/m-p/793903#M2487 Omer_Riaz 2012-03-09T11:10:49Z Pardiso behaviour having right hand side "B" all zero. https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Pardiso-behaviour-having-right-hand-side-quot-B-quot-all-zero/m-p/793904#M2488 This is a guess, since there is nothing specific to explore:<BR /><BR />Pardiso allows iterative refinement, and this can be a problem in the special case where the solution is a vector of zeroes.<BR /><BR />Please show a short example of the problem.
