Don't forget to initiate them for GAMBIT==> write the number of coord and then the number of your matrix (it will be the number of line you have). here is the example __________________________________________________ _____________ 36 1 1.000000 0.001600 0 0.950000 0.012400 0 0.900000 0.022900 0 0.800000 0.042800 0 0.700000 0.061000 0 0.600000 0.077100 0 0.500000 0.090500 0 0.400000 0.100200 0 0.300000 0.104800 0 0.250000 0.104400 0 0.200000 0.101300 0 0.150000 0.093400 0 0.100000 0.078000 0 0.075000 0.066400 0 0.050000 0.051300 0 0.025000 0.031700 0 0.012500 0.019300 0 0.000000 0.000000 0 0.012500 -0.005000 0 0.025000 -0.004200 0 0.050000 -0.001000 0 0.075000 0.002800 0 0.100000 0.006800 0 0.150000 0.014500 0 0.200000 0.021700 0 0.250000 0.028200 0 0.300000 0.033300 0 0.400000 0.038500 0 0.500000 0.038600 0 0.600000 0.035000 0 0.700000 0.028600 0 0.800000 0.020200 0 0.900000 0.010000 0 0.950000 0.004400 0 1.000000 -0.001600 0 __________________________________________________ ______________ 36 is number of point you have 1 is number of matrix you have (it can be number of edge) then save it to your directory ==> run GAMBIT ==> click FILE ==> chose IMPORT==>ICEM INPUT==> chose file you have saved==>on geometri to create select edge==> OK. You will have airfoil !!! Try it!!!
