hi
I made a file that produce for me the location of corners of cells.I should connect them to produce for me the meshes(cells). but as i think there is no way to code it. I wanna show this grid in Tecplot.

A list of node locations does not uniquely define a mesh either for cfd computation or for visualization. This is often called a "point cloud." There must be connectivity information included as well, either implicitly or explicitly. Implicit connectivity requires some detailed knowledge and constraints on your node ordering--say for a stretched cartesian mesh, you could deduce connectivity based on node ordering if you knew the number of nodes in the x and y directions. If your mesh is unstructured, you need to define connectivity, say by providing nodes that group together into cells.

You can refer to gmsh documentation for an example of how this is done:

I agree, check chap.s 3 and 4 in

I had the code on fortran !
If you want , i will send it to you
I think you are iranian from your name !

thanks
but what is the requirements? my written code is very long and i can put the requirement of tecplot on it. but really i don't know the true format in tecplot for generating .DAT file in fortran. your texts was so good but i want to know the requirements to put it in my code.

thanks Mr denaro.
but I don't know the phrases of my problem to search in this PDF. what is named my case exactly? and what is it's requirements in tecplot?

I send you a mail. plz read it.

not more idea???!!!

[mprinkey]

The file format is documented in Chapter 4. If you are doing single-block mapped 2D cartesian grid generation, which I infer from your other earlier question, you should be able to use the IJ-ordered data points format as documented in 3.3.1.2 of that .pdf. The ASCII output for iJ-ordered data is documented in 4.2.2. The information is all there. If you understand how your grid generation works, it should be easy to follow their recipe and turn it into a tecplot file.

Mr mprinkey, FMDenaro and amirhosseintaran
thank to you. finally I learn how to write my Fortran code.
best regards to you.
