The idea is basically to read-in a matrix and rhs, setup GAMG as ksppreonly, get the smoother and overrule it with a python function of my own, similar to the demo where the Jacobi method is user-defined in python. So far I have something like this:<br /><br />pc = PETSc.PC().create()<br />pc.setOperators(A)<br />pc.setType(PETSc.PC.Type.GAMG)<br />pc.PCMGGetSmoother(l=0,ksp=smoother)<br /><br />which triggers the following error:<br /><br />AttributeError: 'petsc4py.PETSc.PC' object has no attribute 'PCMGGetSmoother'<br /><br />1) Am I doing something wrong, or is this function just not available through python? <br /><br />2) How can I tell up front if a function is available, only if it is listed in libpetsc4py.pyx? <br /><br />3) Given the function description in C from the manual pages, how can I deduce the python syntax?<br /> (perhaps it's supposed to be ksp = pc.PCMGGetSmoother(l=0), or something else entirely)<br /><br />Thanks for your help,</div><div dir="ltr"
