Rob thank you for all your suggestions.nI've tried increasing time step but with smaller time step droplet starts to evaporate. nI could try to increasing the surface tension but i need my calculation to invole water, because of analitical comparison. nTo sum up - I have 3 surfaces (upper electrode, lower left and lower right electrode). On all of them I have defined a contact angle 60? except for lower right where i defined UDF for a change. I don't have an inlet or outlet - should I define that? Is it possible that there is a pressure problem? n n
