Hi,
I'm trying to implement the following for a 2D problem:
Set Prescribed velocity boundary indicators = left : function , right : function
But get error when trying to give Function expressions in: set Function expression =
I have tried separating 2 velocity components with semicolon and separate function expressions with comma .
Example:
Left boundary function right boundary function
Set Function expression = if(z>=1000 , 1, 0) ; 0 , if(z>=1000, -1,0) ; 0
I've tried many ways including below but all give errors or nonsensical velocity Glyphs:
Set Function expression = left: if(z>=1000 , 1, 0) ; 0 , right: if(z>=1000, -1,0) ; 0
Set Function expression = left = if(z>=1000 , 1, 0) ; 0 , right= if(z>=1000, -1,0) ; 0
Set Function expression = ( if(z>=1000 , 1, 0) ; 0 ) , ( if(z>=1000, -1,0) ; 0 )
...
How can I separate multiple function expressions each for its corresponding boundary indicator ?
Thanks
Payman
