Yes. It's possible. UDF can access a centroid of face on a cell and access the cell centroid as well.

Then ,the distance from wall can be calculated by vector calculations.

Thanks Keil.

Can a UDF-macro determine the coordinates of the nearest wall in complex geometry?

Regards

Yes. It can.

But the program will be a little bit complex.

Hi Gabor,

Try to use C_WALL_DIST(c,t) macro in UDF... I suppose it is what You need.
