hi
this is the first question.
if someone help me, i will be glad to your help.

now,i am trying to simulate mass transfer mechamism(co2 dissolve in water.)

i use following models.

vof
species transfer
energy
phase interaction(udf)my first udf.txt
patch co2 to a circle in water.
phase-1:mixture(water) phase-2:mixture(co2)

this is my first udf.
i want to put mass sources into adjacent cells (gas-water interface) through my first udf.

i can compile and load this udf.

but,when i push calculate,i get an error(access violation)and co2 phase-1 get only 0.error.jpg
would you tell me how to correct this error ?

thanks!

Hello, were you able to solve this problem? I am trying to simulate the exact thing. Where CO2 comes from the top interface and mixes with water.
