Ansys Meshing doubt
3 Attachment(s)
Hi all,
I am creating a 3d model for a fluid flow in a rectangular channel in order to validate results from a paper (refer attached pic COMPARISON.jpg). Now, i am encountering problem in the contact regions between the fluid and solid as I cannot define biasing on the common edge as shown in the figure (conjugatefig.png). The mesh i require taken from a journal paper is also shown. kindly help as to how I can achieve the same kind of mesh. the basic problem is that i want to isloate the common edge to the fluid part so that i can achieve biasing only in the fluid region and not in the solid region. This way i can remove the skewness in the mesh and achieve straight orthogonal mesh as shown in the reference paper. Kindly help.Thank you. |
Hi,
You need to slice your geometry in designmodeller before importing it into AM. To do so you can insert a plane and then use Create > Slice. You'll end up with smaller "blocks" that can easily be meshed and in your case you can then apply an identical bias for both fluid and solid geometry. |

If you want to have a non-conformal mesh of the fluid and solid and be able to mesh them separately (and also imposing a different bias between the two domains) you need need to have them in different parts in DM.
So if you split your fluid and solid geometry you then need to create a part for the fluid and another for the solid each one containing the respective subdivided domains. |
In DM, select the Fluid part in the tree and set the "Share Topology" option to None. In this way you don't have split the geometry but you will have separate fluid and solid edges/faces.
