Hi Thibaut,

To visualize the potential field on the heart surface, you just need to map the final solution onto the heart surface.  To do this, first extract the heart surface from the segmentation with GetDomainBoundary and selecting the appropriate regions (10 and 11 in the example data, select the range option).  Connect the input of this module to the output of the readfield where the segmentation is read in (make sure the data is on the elements if using your own data).  You can smooth the heart surface using the FairMesh module if you want.  To map the data onto the heart mesh use MapFieldDataOntoNodes with the calculated field (output of setfielddata) as the first input and the heart mesh (output of getdomainboundary) as the third input.  You then use showfield and the colormap modules to visualize it.  The nice thing about the MapFieldDataOntoNodes is that you can map the value (potential field), the gradient (vector electric field), or the gradient norm (electric field strength) by just changing the option in the UI.  you can visualize the vector field as glyphs with ShowFieldGlyphs.  

cheers,
Jess

Hi,
 
I discovered recently SciRun software and the defibrillation tutorial.
I would like to modify the dataflow in order to visualize the effect of a shock on the only heart but taking into account the whole torso, and not on the torso itself as described in the tutorial.
 
Could you give me some guidelines in order to know where to start?
 
Best regards,
 
Thibaut de Geyer
