define profile with multiple threads
Hi all,
I have a domain with a couple of cell threads. I would like to firstly work out the average temperature in one of the threads by looping over the cells. Then I would like to use that temperature to set the temperature at an inlet face in my domain. I tried to do both steps in one define_profile. Define_profile is passed a thread from the solver. If I use the profile on my inlet face then the solver passes the inlet face thread. I tried to bring in the cell thread using Lookup_Thread but I'm having problems. Is it possible to do both steps in the one define_profile macro? |
You should define two threads into that DEFINE_PROFILE, store the thread information into a variable, then call it into the equation of the Profile thread. I have done that before.

2D airfoil O Grid- negative volume
Hi,
I'm carrying out a 2D pitching airfoil simulation using dynamic meshing with a "O" Grid. The dynamic conditions i have given were 1) airfoil - rigid body with UDF with pitching over X=0.25 2)interior - deforming with the min and max length scale from zone scale info 3) fluid -deforming with the min and max length scale from zone scale info. The spring constant i gave was 0.001 and convergence tolerance 0.0001 No of iterations 150. The time step tat i used is 0.001. After running the iterations and after about 500 time steps i'm getting the following error negative volume detected dynamic mesh update failed. i have worked around with the spring constant and also with the time step nothing worked. could someone help me out rectify this issue.. thanks in advance, sam |
