     1These are a list of solvers that have worked fairly consistently, try them out locally and if the recovery solver is not activated, you should be safe for longer transient runs:
     2
     3% biconjugate gradient with block Jacobi preconditioner [Thiago's favorite]
     4md.toolkits.DefaultAnalysis=bcgslbjacobioptions();
     5
     6% germs with block jacobi preconditioned [Martin's favorite]
     7md.toolkits.DefaultAnalysis=gmresbjacobioptions();
     8md.toolkits.DefaultAnalysis.ksp_max_it=1;
     9
     10% ASM, used for mass conservation but may work for other things
     11md.toolkits.DefaultAnalysis=asmoptions();
     12
     13% An iterative solver may work for one analysis and not another, you can assign a solver to each, like this:
     14md.toolkits.StressbalanceAnalysis = gmresbjacobioptions();
     15md.toolkits.DefaultAnalysis=issmmumpssolver();
     16
     17%Keep recovery mode as MUMPS
     18md.toolkits.RecoveryAnalysis=issmmumpssolver();
