How to refine leading edge mesh in TurboGrid 10
 
Hallo everbody. I worked with Turbogrid 2.2.1 and there was a possibility to refine the mesh at leading/trailing edge by changing split factors in MESHDATA/PASSAGE. But in TurboGrid 10 there is not such an options in the PASSAGE options. Can anybody explain me how to refine the mesh at the trailing/leading edge in TurboGrid 10...

Thanks....Christian....

Hi Christian,

It can only be done in the viewer. Right click on the edge you wish to refine and pick Edge Refinement. Values can be floats, and TurboGrid will round it to the nearest integer value.

Regards, Robin

Thank you for the prompt reply, but when i right click on the leading edge, the only available fields are: -Edit -Hide -Color-> -Create Mesh -Set Turbosurface Position

Thanks Christian

The shroud surface is probably in the way. Pick "Hide" and try again.

Hi Robin. The only thing that i found is the "insert edge split control" to change the topology. I donīt know if i do something wrong, but i cannot find an "Edge Refinement".

That's exactly what you need. After you insert edge split control, TG will ask you a split factor. The default value is 1, which means the edge split count on that edge is the same as the global one. If you change it to 2, that edge will have twice splits than other edges.

Thank you. It works. But now i have the next problem. If you imagine the topology in lines and crevices. When i insert the edge split control it changes the the resolution of the whole line or the whole crevice. Is it also possible to change the split of only one or a group of blocks. Do make you understand what im searching for, I have a stator blade and want to make the mesh finer at leading and trailing edge. The Problem is that iīm not really experienced in TurboGrid and th Tutorial doesnīt offer what i need.

Christian.

Unfortunately, a change made on one edge will propagate to topologically matching edges for structured mesh. What you are looking for is actually overset grid. TurboGrid does not have that capability.
