Hi All,

I am creating a mesh for a blade that is placed in a domain. The blade has a trailing edge with a small thickness. I am trying to create my volume mesh by first creating a patch dependent surface mesh and then using a Delauney volume mesh over this.

I have obtained my patch dependent surface mesh as shown in Figure 1. However, when I create my Delauney volume mesh over this, the volume mesh forms incorrectly and goes outside the domain.

I made sure that when the fluid-material point is being created, it is outside the blade and inside the domain. I have attached Figure 2 to indicate the wrong volume mesh.

I have also made sure to delete the common surface that was present between the blade and the symmetry surface of the domain.

Could anybody please tell me how I can go about to correct this.
Thank you!

I got my volume mesh correctly. I had not done build topology correctly earlier.
