Hi everyone,<\/p>\n

I want to block the following 3D airfoil in ICEM and create a structured mesh for it.<\/span><\/span><\/span><\/p>\n

\"\"<\/span><\/span><\/span><\/p>\n

 <\/div>\n
I blocked it as below<\/span><\/span><\/span>, which according to the figure below has 5 blocks, 3 of which are in the front, top and bottom of the airfoil and 2 of which are behind the airfoil.<\/span><\/span><\/span><\/div>\n
 <\/div>\n
\"\"<\/span><\/span><\/span><\/div>\n
 <\/div>\n
Now, I have created an initial mesh on the created block, which is as shown in the figure below:<\/span><\/span><\/span><\/div>\n
 <\/div>\n
\"\"<\/span><\/span><\/span><\/div>\n
 <\/div>\n
According to the figure above, the mesh in front of the airfoil (front block) has less density than the upper and lower blocks of the airfoil and is not uniform.You might say that the problem can be solved by increasing the number of relevant block nodes. But it is not. I increased the number of nodes. See the figure below:<\/span><\/span><\/span><\/div>\n
 <\/div>\n
\"\"<\/span><\/span><\/span><\/div>\n
 <\/div>\n
According to the figure above, the mesh of all three blocks is uniform, but the mesh near the airfoil has a very high density, which does not seem appropriate.<\/span><\/span><\/span><\/div>\n
 <\/div>\n
Is there a problem with my blocking, and for example, those two diagonal lines of 45 degrees that are connected from the airfoil to the big half circle of the domain, should they be diagonal or vertical?
<\/span><\/span><\/span><\/div>\n
 <\/div>\n
I found a picture of a grid on the internet, which seems to be a well-formed uniform front grid of the airfoil, which looks like this:<\/span><\/span><\/span><\/div>\n
 <\/div>\n
\"\"<\/span><\/span><\/span><\/div>\n
 <\/div>\n
Is its blocking different from mine?<\/span><\/span><\/span><\/div>\n
 <\/div>\n
What kind of blocking strategy should I develop in order to achieve a proper and uniform mesh in front of the airfoil?<\/span><\/span><\/span><\/div>\n
 <\/div>\n
Thanks in advance<\/span><\/span><\/span><\/div>\n
