title: How do I format a PLOT3D file for ParaView?
body: <p>I'm trying to describe the shape of a rabbit heart in order for simulations to be visualised with ParaView.</p>
  
  <p>The problem I'm having is that ParaView would like the geometry to be described in PLOT3D format, a clear description of which I'm struggling to find online.</p>
  
  <p>The geometry I have consists of a regular 3D mesh, from which only some points are tissue -others are in the space around or inside the chambers.</p>
  
  <p>I'd be grateful if anyone with experience of this format, or who can make better sense of the online documentation could help me out.</p>
