Mesh via triangle failed

I attempted to split a segment to a smaller size than

  floating point arithmetic.
Try increasing the area criterion and/or reducing the minimum
  allowable angle so that tiny triangles are not created.

It is truly disgusting that I can't add the screenshot easily. What may be the cause for this error and how can I solve this error?

Re: Mesh via triangle failed

I changed the boundary again and performed and could make quality mesh, interpolation and export the mesh in basemesh v1.4.6 but I couldn't make stringdef file. i get not responding again and again.
