Pierre-<br><br>To be honest- creating an adaptor is hard. (That's we have been paid to do it :-)) Yes, we have gotten it working in ParaView, I'm going to refer you to Francois Bertel who may have some something more to add.<br>

<div>Hi Will,</div>
<div> </div>
<div>I thank you for your help! This paper is indeed very interesting.</div>
<div> </div>
<div>I think that it contains many answers to my problems. However, I do not really see how to make use of this framework yet.</div>
<div>- are there somwhere some tutorials listing the classes to be used, and giving some examples of how to manage FEA results with them? (somehow something close to the pdf I sent previously)</div>
<div>- can the data structure be then used in ParaView? I guess that specific filters may have to implemented, haven't them?</div>
<div> </div>
<div>Thank you again,</div>
<div>Best regards,</div>
<div> </div>

This may help shed light on the topic. The point is, rather than trying to shoehorn FEM data structures into VTK (which is not pretty), you can build adaptors from VTK to native FEM codes and data structures.<br>

<div>Hi all,</div>
<div><span>
<div> </div>
<div>I would like to have information about the best way to handle FEM data in VTK file.</div>
<div> </div>
<div>Mainly, we use shell meshes (triangles or quadrangles) and the following data would be manipulated in VTK:</div>
<div>- reduced element or fully integrated (1 or 4 integration point in the neutral fibre)</div>
<div>- different integration point over thickness per element (1, 3, 5, 7, 9, 11, ...)</div>
<div>- different integration algorithms over thickness (GAUSS, SIMPSON, ....) defining different weight and locations of these integration points over thickness</div>
<div>- stress tensor at each integration point over thickness</div>
<div>- strain tensor at each integration point over thickness</div>
<div>- effective plastic strain at each integration point over thickness</div>
<div>- thickness at each integration point in the neutral fibre</div>
<div>and possibly additional results per integration points...</div>
<div> </div>
<div>This topic seems to have already been tackled.</div>
<div>Indeed, I have read several posts about the vtkLSDynaReader class, as well as its documentation on </div>
<div><a href="http://public.kitware.com/VTK/doc/nightly/html/classvtkLSDynaReader.html" target="_blank">http://public.kitware.com/VTK/doc/nightly/html/classvtkLSDynaReader.html</a></div>
<div> </div>
<div>As it is indicated in one of the post, the ultimate goal would be to benefit from vtk format/library to manipulate FEM data, and from ParaView as PostProcessor</div>
<div> </div>
<div>However, from these posts, it seems that VTK is not really fitted to store FEM data, and for such a purpose, a good knowledge in VTK is necessary. It may also be necessary to extend it.</div>
<div> </div>
<div>Most notably, it seems currently possible to have only one scalar field, vector field, and tensor field per element. In the last VTK versions, has this "limitation" been overriden?</div>
<div>Is it possible to store several fields of different types per element?</div>
<div> </div>
<div>Would you have some advices about the best way to proceed?</div>
<div>Is there somewhere some guidelines/tutorials?</div>
<div> </div>
<div>It the VTK format has still some limitations, is it foreseen to override them in the next release?</div>
<div> </div>
<div>I thank you for your help.</div>
<div> </div>
<div>Cheers,</div></span></div></div><br><span>_______________________________________________<br>vtk-developers mailing list<br><a href="mailto:vtk-developers@vtk.org" target="_blank">vtk-developers@vtk.org</a><br>
