<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt">Hello <br>
<br>
I am using a external library to vtk with MPI <br>
<br>
I have my code this way:<br>
<br>
void vtkXYZReader::DistributeData(vtkSmartPointer<<span class="bold1">vtkMPICommunicator</span>> commtr) {<br>
external_Lib_Init(MPI_COMM_WORLD);<br>
....<br>
}<br>
<br>
well this works, but it is not elegant. How can I get the MPI_Comm from "commtr" ?<br>
<br>
like :<br>
external_Lib_Init(commtr->GetMPIComm ()); <br>
<br>
this is unfortunately not of type MPI_Comm but of <span class="bold1">vtkMPICommunicatorOpaqueComm</span>*<br>
<br>
Thanks in advance</span><span lang="EN-US" style="font-size:10.0pt; font-family:"Arial","sans-serif""></span></p>
