Hi,<br>
I'm looking for how to get information about the DA of a DMMG finest grid.<br>
I saw that you can access them with<br>
call DMMGGetDA(...<br>
call DAGetInfo(...<br>
but it doesn't work in the main program, i get this error<br>
0]PETSC ERROR: Invalid argument!<br>
[0]PETSC ERROR: Wrong type of object: Parameter # 1!<br></blockquote><div><br></div><div>1) Always send the COMPLETE error message</div><div><br></div><div>2) That should work. Notice that we use that on line 75</div><div>

I tried with this example<br>
<a href="http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/ksp/ksp/examples/tutorials/ex22f.F.html" target="_blank">http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/src/ksp/ksp/examples/tutorials/ex22f.F.html</a><br>
<br>
I don't know how to get DA infos outside the subroutines ComputeRHS and ComputeJacobian<br>
<br>
I want grid size of the DA 3D in order to plot the field. I noticed that it's possible with PetscObjectQuery in C language.<br>
<br>
Thanks for your help<br>
