I have a .dat file of a airfoil but i can not input it into gridgen, what can i do? cheers

Here's an e.g. just follow the same style. btw, 1st line is no. of coordinates to be entered. Then followed by the 3d coordinates

201 0 0 0 0.005 0.012213147 0 0.01 0.017037074 0 0.015 0.020636712 0 0.02 0.023597771 0 0.025 0.026147199 0 0.03 0.028401445 0 0.035 0.030429739 0 ....

go to DB in gridgen and import the dat file. after that, create connectors based on DB.

hope that helps.

Hello "a whole new world".

zonexo is correct. The first step is to ensure that your file has the correct format. Gridgen's so-called segment files (.dat) are expected to contain a string of points like this:

N

x1 y1 z1

x2 y2 z2

...

xN yN zN

In fact, you can have several curves in the same .dat file.

Also, you can import the segment (.dat) file as a database entity as zenexo suggests but you also have two other options.

1) You can import it a connector shape.

2) You can import it as connector grid points.

Hope this helps.
