Mesh Reference Values problem.

rezki · July 19, 2010, 05:11

Hello,

I want to create the following example of the tutorial:
Training Guide > Meshing Tutorials > Control Valve Meshing Tutorial.

When I arrived at Setting the Global Mesh Reference Values step :
(Training Guide > Meshing Tutorials > Control Valve Meshing Tutorial > Polyhedral Meshing Exemple > Setting the Global Mesh Reference Values)

I could not to change mesh Reference values

For example, I could not introduce the value of 4.0 into: Prism Layer Thickness > Relative Size > Percentage of Base, a value of 33.3 is always imposed and it remains unchangeable.

Please, What can be reason for that ?

Best regards

hmmm 1-st: relative to base ->percentage of base, then your prism layers will be "percenatge" depend. 2-nd: change relative to base->absolute size and then add your constatnt value

Hi,

Thank you very much for your help.
Ok, but in the tutorial, they recommended to use relative to base.

The parameters which will be used for this meshing tutorial are here:

Reference Node Name

Property Name

Value

Base Size

Value

0.06 m

CAD Projection

Project to CAD

true (default)

Number of Prism Layers

2 (default)

Prism Layer Stretching

1.5 (default)

Prism Layer Thickness > Relative Size

Percentage of Base

4.0

Surface Curvature

# Pts/circle

36 (default)

Surface Growth Rate

1.3 (default)

Surface Proximity

# Points in a gap

2.0 (default)

Surface Proximity

Search Floor

0.0 (default)

Surface Size > Relative Minimum Size

Percentage of Base

4.0

Surface Size > Relative Target Size

Percentage of Base

8.0

Tet/Poly Density

Growth Factor

1.0 (default)

Tet/Poly Density

Density

1.0 (default)

Tet/Poly Volume Blending

Blending Factor

1.0 (default)

Best regards.

ok, I agree, but what do you do when you want to have 6 mm prism layer thickness ( how many percentage ?? ) ? I think that better way is using absolute size and have maximum control of prism layers thickness

Hi,

Thank you very much for your help.
Ok, but in the tutorial, they recommended to use relative to base instead absolute.

Base Size > Value > 0.06 m

Prism Layer Thickness > Relative Size > Percentage of Base > 4.0

Surface Size> Relative Minimum Size > Percentage of Base> 4.0

Surface Size > Relative Target Size > Percentage of Base > 8.0

Best regards.
