Hi,
I'm using Phoenics as part of WindSim. I'm trying to figure out ways of checking convergence after a run has been completed by using the .result file I get from Phoenics. Using the MIGAL solver, I get a list of residuals (Max, Min and RMS) for each iteration. Would it be appropriate to use these values to check convergence? I'm concerned whether the values provided are whole-field values or stems from a single location? Also, Which variable are the residuals showing; just the overall largest and smallest? Further, can somebody help me understand the section shown below? I'm having trouble deciphering it. ************************************************** ********** Whole-field residuals before solution with resref values determined by EARTH & resfac= 1.000000E-01 variable resref (res sum)/resref (res sum) P1 1.232E+05 1.383E-02 1.703E+03 U1 1.137E+06 2.078E-02 2.363E+04 V1 6.845E+03 7.748E-01 5.303E+03 W1 2.626E+04 5.407E-01 1.420E+04 KE 3.566E+03 6.060E-01 2.161E+03 EP 3.189E+01 5.820E-01 1.856E+01 ************************************************** ********** Thanks for your help guys. Any comments are appreciated. And sorry if I'm asking stupid questions ;-) |
