3d elliptic generation mesh
I need a source code for structure mesh generation with 3d elliptic equations. I am appreciate if someone told me the site which has the code

Re: 3d elliptic generation mesh
If you haven't checked Robert Schneider's grid generation site you should look there  it has many links to free mesh generation software. Click on "Resources", "Topic" above and locate the "Mesh Generation" section. There is a link to this site there. I'm sorry that I can't give you a direct reference, perhaps someone else can...

Dear Mr.J.Larsson, Thank you very much for your suggextion. I have checked the Schneider's site and links, but I did not get the site I need.

Re: 3d elliptic generation mesh
The 2D elliptic mesh generation code was published many years ago in NASA report. It's also available in a book on numerical mesh generation. In 3D case, geometry itself is a rather complicated issue. You need to understand the 3D geometry topology and construction, surface mesh generation and so forth. The control of mesh density and convergence is also complicated. I would suggest that you first study the topology of the geometry you are trying to solve. Then develop an approach to create the geometry. As for the mesh generation, you can divide the computational domain into structured blocks. Most of these blocks will be interior blocks which are very easy to handle using simple algebraic mesh generation method. ( straight lines are usually good enough if the block is constructed using straight lines and planes) For the blocks which include wall or boundary, normally you can use simple interpolation method to generate the 3D mesh. Don't worry about the quality of the initial mesh because once you have the solution of the flow field, you will come back to refine the mesh by moving the block locations or geometry. In this way, you can control your mesh. The mesh control is very important to the accuracy of your solutions. ( mesh control and convergence can be a difficult issue in the 3D numerical mesh generation. In 3D, it is not easy to check the final mesh quality. )

Dear Mr. J.C.Chien, I am very appreciate that you recommand me another method for complicate configuration mesh generation. Up to now, I have studied many methods includes algebraic,hyperbolic, and 2d elliptic(ch), but it is very difficult to control the distribution. My solver does not have the multiblock function, and many years ago, I had try to solve the 3d elliptic equations for mesh generation, I did fail, so many years passed, I want to taste to generation 3d mesh with elliptic method. In addition, I have many 3d surface mesh distribution.

Re: 3d elliptic generation mesh
I am completing my final undergraduate year in Mechanical Engineering at Queens University, Kingston Ontario Canada. I am beginning by studies in the field of CFD and enjoyed your description of 3d Elliptic Mesh generation. I look forward to futher clips.
