Thanks a lot!Just checked icem, and there is an option to save as plot3d. I'll try that procedure first - seems easier to get going with (but less flexible). Another advantage is that in our group (except me only working with openfoam) we are used to icem, and it might be a bit easier to convince them to try overture if they still can use icem ;-)

Hi Jon, In principle you can import any collection of structured grids as DataPointMappings. As I recall ICEM has a block structured grid generator; you could import the individual blocks as DataPointMappings and then generate an overlapping grid with ogen. If ICEM can write the blocks using the plot3d format then we even have a reader for that, otherwise you will need to translate the grid data into a format ogen can read. To generate grids from CAD we usually use our in house tools ogen, mbuilder and rap. ogen is the most general tool and actually includes all the functionality of mbuilder and rap. The sample CAD-data grids are a good place to start (asmo*.cmd, marsCapsule.cmd, nozzleAndCavity.cmd); run them interactively to get an idea of what is going on. However, some of these scripts can be long and a little cryptic. After running through them I suggest you read in one of the IGES files and try it out; in my experience trial and error is the best way to learn these things :-) Usually we start by generating the grids interactively and then modify the saved command file (ogen.cmd) in order to parameterize the grid generation process (grid resolution, geometry changes, etc). Let us know if you have any questions. Regards, Kyle mailto: chand1@xxxxxxxx phoneto: (925) 422 7740 On May 25, 2011, at 3:28 AM, Jon Tegner wrote:Great! Looking forward to try it! Have a general question. I have some experience of meshing using ICEM. Is it possible to import meshes made from ICEM (or some other meshing software) into the framework of overture? Generally, what is considered the "best" way of creating the grids of more complex geometries (importing from ICEM or the like might be stupid/not possible)? Would it be to to import CAD-data and then work with that, using ogen? What are the best way to learn this? I saw there is an example in sampleGrids, should I start there?
