Difficult ICEMCFD question: Extrusion

Hi all,
I'm sure you have all used the mesh extrusion function at some time: The fixed distance extrusion is simple enough: Total extrusion distance = Extrusion distance x Number of layers However, I'm trying to use the "Function" option i.e. extrusion distance is controlled by a function. The manual is completely silent on how to do this. I think it probably requires a TCL function input but I dont know how to do this and again the manual is silent Does anyone know how to do this? Thanks! |

Here's a screen shot of a function with explanation. If you give me an ftp area for where to put it, I can give you an Excel spreadsheet.

Awesome. Thanks. This was driving me nuts!
Could you email it to me? ppjjones@gmail.com Most of the web share services force you to jump through endless loops. |

Awesome. Thanks again.
To think I just needed to use the layer keyword |

When I try to use an exponential function for the cell height: 0.0125*1.25^(layer-1), ICEM responds with "Error: can't use non-numeric string as operand of "^"" How can I solve this?

Looks like a question for your support provider - or try ** instead of ^ to see if that allows it.

The correct syntax is: 0.0125 * pow (1.25, layer-10

Sorry, I don't want to dig a 5 years old thread, but it doesn't work. Someone could tell me the correct syntax for an exponential function?

I've sorted out writing:
"height of first layer" * (1+ "arbitrary number "*(layer-1)*(layer-1)*(layer-1)) |
