I have used Simscale for external flows simulations. I have noticed that mesh quality tends to be poor in the transitional zone between 2 region refinements with different element sizings (e.g. high aspect ratio). This usually leads to aphysical results in this zone. Is there a way to create smoother transition?
The picture below, I set 2 region refinements and you can easily see the bad elements situated on the boundary of each region, forming a box-like shape.
Hey Boris, could you also add the link to your project please?
here is the link
The model is Surge ver 1
The result is obviously unreasonable and does not converge
Hi there, this was not meshed with the Standard mesher, right?
It’s a result of standard mesher with the active hex-core element option
Hi there, in that case, I would recommend that you check the following page:
And there is this new advanced option on the main mesh tab so you can control the expansion ratio of neighboring cells globally:
