stops with no error
 

dear friends

i have a question about fluent
i could successfully compile 2 mass transfer udfs and a udf for monod reaction eq.
these udfs can be either interperated or compiled and hooked without a small error
before compiling these udfs i run the steadystate simulation for the hydrodynamics of the problem
now i changed the solver to transient,compiled all 3 udfs ,hooked them
all these processes was without any error
but when i run the simulation in transient,the simulation in the first iteration after reservation of flow in the pressure out let stops,with out printing any error messege. it just stops and the cursor turns from processing mode to regular mode
do u know any solution to this problem?
regards

i might add that i solve the problem in parallel mode
i have parallelized my udf
any fresh idea?

Maybe a silly question, but did you set the number of time steps to be something bigger than zero?

yes my friend,any other suggestions are appriciated
