Hi Friends,<\/span><\/p>\n

I have an issue with the mesh refinement in the water tight workflow and was hoping someone could give me some guidance.<\/span><\/p>\n

I have a simple structure made up of vertical and horizontal plates – see P1.  The windward plates have holes in this version.<\/span><\/p>\n

\"\"<\/p>\n

I have all of the faces named so I can control the face size on each plate using the local facesize tool. I have different sizing on the faces and edges of the vertical plates compared to the horizontal plates.  The intention is to have a finer mesh around the corners of the vertical plates causing separation, coarser on the horizontal faces.<\/span><\/p>\n

Where the vertical plates meet the horizontal plates there is an automatic mesh refinement of the corner zone as expected – see P2. The view here is underside of top horizontal plate.<\/span><\/p>\n

\"\"<\/p>\n

The problem I have is that this refinement is reflected onto the top surface of the upper plate – see P3.<\/p>\n

\"\"<\/p>\n

One issue with this is it increases the overall mesh size for the problem – especially when inflation layers are added.<\/span><\/p>\n

However my main concern is the transition between the coarse mesh to fine then back again along the top flow surface – the mesh does not look good, which makes me concerned about quality of simualtion. – See P4, P5 and P6. I have used poly-hexcore.<\/span><\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Does anyone have a suggestion how I can fix this so that the top face has consistent larger size alomng full length (with exception of edge transition zones?)<\/span><\/p>\n

Thanks<\/span><\/p>\n
