Hi,
I have a problem that when I run the CFX-solver. I have two domains in my cfx model, which are a mould (steel) and hot polymer, respectively.Through 1st simulation run (this represents 1st cycle of injection moulding process) where hot polymer's temperature, 204C is given only initially (i..e, initial condition for the hot polymer domain), we can get some temperature distribution of the "mould domain" at the end of 1st simulation. Then, I want to use this temperature distribution of the mould obtained from the 1st simulation run as initial temperature of the mould for 2nd simulation run ( 2nd cycle of injection moulding process) while old polymer (in the 1st cycle) is replaced by the new one with the same temp., 204C initially used for 1st simulation run (1st cycle) and thus the same initial condition for the "hot polymer domain" should be given for the 2nd simulation run. In brief, I just want to use the previous result file to provide initial values (temp.) of ONLY "the mould domain" for the next simulation, because the polymer's initial condition should be the same for every cycle (every run)." When I used the 1st run's result file (res) for the 2nd simulation with the option of 'Interpolate initial values onto Def file mesh', the 2nd simulation properly uses the temp. of "the mould domain" obtained from 1st simulation result file as initial value, but the initial condition (204C) of the "hot polymer" for the 2nd simulation which is the same one for the 1st cycle is not maintained. (i.e., the initial condition of the hot polymer is ignored in the 2nd simulation run). Please let me know how to solve this problem. Thank you so much. Jaho |
