Droplet Impact on Structured surfaces UDF.
Dear Ansys Community, hope you shall be in good health. i need help because i am facing some problem regarding droplet impact on the structured surface.
i am doing a 3D simulation for analysis of droplet spreading behavior on the structured surface.
i have written the udf is attached in the pictures.
To get spreading behavior/spreading factor/liquid-air interface the
is used in the udf.
1) the problem i am facing right now when the droplet hits the structured surface the fluent crashes every time.
2) if I remove that command mentioned above in the udf the fluent runs perfectly.
can you help me to fix this issue?
I need to use this command to get the spreading factor of the droplet impact.
i also attached the udf pictures and geometry pictures in the form pictures.
please reply urgently.
i have a due date of the project in my University.
