Hello Ron,<br> I do not know how your are actually including the files and compiling. Have a look at the attached example illustrating petsc usage in Fortran, i tried to make the structure similar to the code you posted. You should be able to test it by (1) make test and (2) ./test<br>

Thanks for the kindly reply.<br><br>By saying petscdef files, do you mean petscXXXdef, where XXX is the corresponding component of PETSc, such as vec, mat, et. al.?<br><br>I tried the following approach, but it still doesn't work. The errors come out since there are some PETSc variables defined in Module MyParameter. The compiler cannot find PETSc datatype. The conflict is that some PESTs variables have to defined in Module MyParameter, and other PETSc variables and PETSc subroutines are defined and called in another Module MySub. Any hints and suggestions would be appreciated very much. Thanks.<br>
