Thank you so much Simon..

Think wedges would be great but I am not sure how to apply. So far I just cut orthogonal to existing edges. I do start with a cube surrounding the entire model (3D...

Hi everyone, Hi Simon,

I do have another problem..

Did change the configuration of the geometry. Now I have the problem that at a certain point two curves meet tangentially. There I do have...

Dear Simon,

these are really lots of options. I think I will first try to use FLUENT to interpolate. I will report the experience I gonna make.

Thank you very much.

Dear Simon,

I think blocking all at once will be possible but in the end I do not want to have the complete geometry within the same case file because this will result in too many cells. I would...

Hi Simon,

I now want to block the environment too. I want to do it seperately. I want to use the outlet condition as inlet. Therefore I would prefer to use exactly the same grid for the inlet...

I think I will keep the blocking for the internal region. Is it possible to coarse the mesh throughout the far field? I do know that I can cause a coarsening with increasing distance, but the number...

Thank you.
In case of conjugate heat transfer calculation I would mesh the solid part too, right?

Dear Simon,

thank you very much for your advice. I gonna try to re-block the entire structure. I think this will be more difficult because I will have to model a defined wall thickness. I will...

Dear Simon,

I am not familiar with the method of non conformal interfaces. From what I have read it enables me to define several domains which must not necessarely have contact and FLUENT will...

Dear Simon,

I do know about the necessity of a grid independence study but in fact I have not been able to perform one because of the lack of an appropriate o-grid which lead to an decrease of...

Hi Simon,

incredible how the grid quality did improve.:)

Thank you very much.

What kind of length ratio would you recommend for the cells throughout the slot. The actual cells are very long...

Hi Simon,

did you use some kind of index control? I think I was able to block it the same way you did. There are two more questions:
Do I have to link the edges before or after snapping the...

Hi Simon,

the linking is clear but how exactly did you create the O-grid. Did you use the same splitting I used? Which blocks and surfaces did you include and how did you modify the O-grid...

Hi,

it is me again. Now I found out that it is possible to read hexa mesh into FLUENT.
But the problem I am now faced with is the transition zone between the inlet (tube) and the cavity. The...

Very Different Length Scales

Hello Everyone,

In the moment I try to model a "Slot Die" (3D). The first problem I was faced with was the very different length scales. While the Inlet and the cavities have diameters of...
