<DIV>I use the following code to attach the arrays to the mesh.</DIV>
<DIV> </DIV>
<DIV><FONT face="Courier New">if(first == 0) {<BR><SPAN style="mso-tab-count: 4"> </SPAN>output->GetCellData()->SetScalars(cell_data_array[j]);<BR>} else {<BR><SPAN style="mso-tab-count: 4"> </SPAN>output->GetCellData()->AddArray(cell_data_array[j]);<BR>}</FONT><BR></DIV>
<DIV>where output is a vtkUnstructuredGrid, and cell_data_array is an array of pointers to vtkFloatArrays.</DIV>
<DIV> </DIV>
<DIV>I am not using a debugger, but I will run in valgrind and see what I come up with.</DIV>
<DIV> </DIV>
<DIV>Thanks for the help.</DIV>

<DIV style="COLOR: #000000">How are you associating the data with the vtk dataset? Do you read an array and hand it to a vtk array? Also, can you run in a debugger and get a track trace? If you are running on Linux, valgrind would be even better.<BR><BR>-Berk<BR><BR>

<DIV>Hi all,</DIV>
<DIV> </DIV>
<DIV>I wrote a custom reader that brings our simulation results into ParaView. </DIV>
<DIV> </DIV>
<DIV>The data is an unstructured grid with multiple timesteps. The cells are either hexahedron or wedges. The data I attach to the mesh is mostly scalar with a few vectors.</DIV>
<DIV> </DIV>
<DIV>With most of the simulation results we look at the reader looks fine, but some of the data sets cause the following error.</DIV>
<DIV> </DIV>
<DIV>free(): invalid pointer 0xc2f7f70!</DIV>
<DIV> </DIV>
<DIV>This error happens after my code executes and I have returned the unstructured grid over to ParaView.</DIV>
<DIV> </DIV>
<DIV>I have done the following to debug the problem:</DIV>
<DIV> </DIV>
<DIV>1. I checked the number of arrays that I am attaching to the mesh and the NumberOfCellFields variable, these match.</DIV>
<DIV> </DIV>
<DIV>2. I checked the MaxId of all the arrays. These match the cell count.</DIV>
<DIV> </DIV>
<DIV>3. When I turn all the cell arrays off, I don't get the errors, and the mesh loads.</DIV>
<DIV> </DIV>
<DIV>Does anyone have any ideas on what the problem could be?</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV><SPAN class=sg>
