ESyS-Particle

Edge contained in 3 triangles

Asked by Toketo

Hello guys,

I was running a program till I saw this error:

[err] Edge contained in 3 triangles ??

What does this mean? It still continued to run constructing fieldsavers. Is the problem about the mesh? Characteristic length is 1.0. Should I divide my mesh into smaller pieces?

Instead of fieldsaver, it continued to construct:

constructing FieldMaster for field velocity
constructing FieldMaster for field position
constructing FieldMaster for field v_abs
constructing FieldMaster for field potential_energy
constructing FieldMaster for field e_kin
constructing FieldMaster for field e_kin_linear
constructing FieldMaster for field e_kin_rot

Hi Toketo,

> [err] Edge contained in 3 triangles ??

The error message suggests that your mesh is topologically non-planar, but ESyS-Particle currently only supports meshes with a planar topology, i.e. an edge can belong to one triangle (in case of a boundary edge) or to two triangles (an internal edge).

So what should I do then to avoid this error?

Oh okay. I kinda bit created a complicated mesh. I forgot that esys could also create infinite walls. Thanks by the way Steffen!

Thanks SteffenAbe, that solved my question.
