Scripted Mesh Generation Software
I'm looking for a mesh generation software that
is free and open source,
provides a sane scripting interface for domain specification,
works for complex geometries,
can generate 2D and 3D meshes,
What options do I have?

Mesh Generation in 1-D
I am using the method by Brandt in the FAS Multigrid algorithm to estimate the truncation error in a 1-D flow problem and then use that as the basis for generating a mesh(r-adaptation) in 1-D.
The process is standard, in that, transform the…

Isosurface extraction when you know the derivatives
I have a complicated equation that defines a shape in 3D, and I would like to generate a surface mesh. The shape is defined by an isosurface, i.e. the function is positive inside the shape and negative outside it.
The standard basic technique for…

Mesh generation with mostly the same elements (type/size..)
I'm searching for a way to generate a mesh that consists mostly of the same elements and i mean not only the same type, but the exact same size to ease the FEM-calculation.
Is there a particular algorithm or software package i should look into?

Filling a volume with generalised polyhedra
Given a volume (say, some polyhedron), I need to fill it with smaller polyhedra, such that the space is filled as much as possible. The constraints and relaxations are:
(0) For a computation perspective, the number of small polyhedra is low, perhaps…

structured to unstructured grid - calculating volume of cell
I have a 3-D structured grid that I am trying to convert over to an unstructured grid.
Here is a picture of the 2-D structured grid with the nodes shown. It is axisymmetric about the x axis (y = 0). I will rotate this to make it 3-D.
My main…

how could I produce triangular mesh for membrane
It is necessary for me to produce triangular mesh on a sphere membrane.
I use MATLAB pdetool or delaunay for produce mesh.
How could I do this?
