hey,

I am trying to apply setFields on https://drive.google.com/file/d/10BI...ew?usp=sharing , a background mesh created using Salome and it is not working.
the new alpha.water field file is not being created (No error message is shown in the terminal). following is my setFieldDict

/*--------------------------------*- C++ -*----------------------------------*\

I would greatly appreciate any help to fix it.
Thank you in advance

Hi,

Please double check the coordinates of 'box'. These coordinates define the region for which you want to set alpha.water to 1. In other words, alpha.water value is set to 1 only for cells that their centre lie in the defined box region. In your 'setFieldDict' file, 'box' is defined as a line from z = (1, -0.8271, -0.601) to z = (1, -0.8271, 0).

Cheers

Hey Rango,

when I searched the syntax of boxToCell the syntax came up as

box (<minX> <minY> <minZ>) (<maxX> <maxY> <maxZ>);

I thought it was supposed to be from minimum point ti maximum point till I have set alpha.water as 1.

I think I might be wrong

Can you help?

Kind regards

Hi,

The syntax is fine. The dimensions of the box might be the issue. Size of the bounding box is equal to |(maxX - minX) * (maxY - minY) * (maxZ - minZ)|, which in your case is zero! I have attached a simple schematic of 'box' dimensions. Hope this makes it more clear for you.

Cheers
