Hi there,

I need to generate a random value of contact angle (CA) between 60 to 90 deg, constant during the simulation over a solid surface, I wonder if somebody give me some points how it can be done. this random values should be in big size of random shaped blobs (e.g. including more than 100 neighbouring surface cell with a similar CA of 65, 69.6,...., 90), so I need to have solid surface with such random blob of varius CAs

*prefereably using expressions or UDF or using any other approach

if using the expressions capabilities that is not posssible using UDFs which macros I need to use?

thanks in advance,

Amir

Hi,

You can try UDF for this case. You can refer to previous forum discussion where contact angle is changed in the UDF.

Hope this helps you.
