Dear friends,
There is one thing I cant figure out. I interpreted my UDF which was made as follows: Define_init function. Is to examine the geometry parameters, to simplify it, it returns the total volume (c_tot variable) of the cells. Define_source (whatever define macro), uses this value, such as x/c_tot. Everything works fine, until I end the calculation, write a .dat file and restart the calculation without initialization. Seems to be (and Im pretty sure), that Fluent does not store the c_tot value, in general any value, obtained from define_init once the calculation is over and then restarted. I really dont want to use a define_adjust (it will uselessly slow down my calculation), or define_on_demand (want to keep it to be performed automatically). Is there any way to store that value for the next usage? Thank you in advance. j. |
