<p>The key is to identify the topology of your surface.</p>
<p>In this case it appears it is a scaled version of the Schwarz P surface, which has the same topology as the <a href="https://en.wikipedia.org/wiki/Regular_skew_apeirohedron" target="_blank">mucube</a>.</p>
<p>So you can generate your clean mesh topology just from subdivision of a cubic form like this:</p>

<p>A decent result, but still quite a few unnecessary singularities in there considering the overall object topology. If the aim is for construction (as in the reference photo) it'd be better to start from an improved position and re-apply a subdivision/relaxation approach.</p>

<p>How did you get the mesh to begin with? Did you start from a simple topology and then get the minimal surface approximation using MeshMachine or some other similar approach? You'll want to manage it from the start of the process, rather than trying to take an unstructured mesh like this and get the type of regular results you're looking for.</p>

<p>Try the Catmull-Clark Subdivision from Weavebird. It subdivides the mesh in quad faces. Is that what you are looking for?</p>
