How to split one quadrilateral element into four triangles?
I want to split all the quadrilateral elements in the mesh into four triangular elements. For example, drawing the two diagonals of a square element.
Re: How to split one quadrilateral element into four triangles?
menu: Mesh->Edit mesh->Split elements->Quadrilateral to triangle
and select the quadrilaterals you want
write
1:
or
1:end
in the command line to select all (or select them in the screen graphically)
Before to use the tool set the preference
Utilities->Preferences... Meshing->Structured: Symmetrical structured: check on Triangles
-with symmetrical triangles set the split will create four triangles and an extra center node
-without symmetrical triangles the split will create two triangles and any extra node
and select the quadrilaterals you want
