Hello Is it possible to reread the options file since I like to experiment different solver configuration during time stepping?
In addition, I got an error with FIELDSPLIT when a split has zero size (That happens in the first step when one field is disabled). Below is the error message on the proc 0: [0]PETSC ERROR: ------------------------------------------------------------------------ [0]PETSC ERROR: Caught signal number 8 FPE: Floating Point Exception,probably divide by zero [0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger [0]PETSC ERROR: or see http://www.mcs.anl.gov/petsc/documentation/faq.html#valgrind [0]PETSC ERROR: or try http://valgrind.org on GNU/linux and Apple Mac OS X to find memory corruption errors [0]PETSC ERROR: configure using --with-debugging=yes, recompile, link, and run [0]PETSC ERROR: to get more information on the crash.
