Hi all,
I've been looking in the manuals for information on the particle tracking file. Does anyone know what the variables that CFX outputs into its .trk file from particle tracking. I tracked one particle stream and opened the .trk file in notepad which gives this: 105 1 -2.000000 4.520412 4.128771 0.0000000E+00 0.0000000E+00 4.9999999E-06 7662425. 1.000000 0.0000000E+00 0.0000000E+00 6.5253494E-14 1 -1.900000 4.520165 4.128793 0.1539223 0.1000004 4.9999999E-06 7662425. 0.6268228 -2.4222441E-03 2.1734087E-04 6.5253494E-14 1 -1.538350 4.518776 4.128928 0.7284727 0.4616528 4.9999999E-06 7662425. 0.6330290 -2.2362103E-03 2.4497270E-04 6.5253494E-14 1 -1.301596 4.517958 4.129019 1.101518 0.6984086 4.9999999E-06 7662425. 0.6369488 -2.1575745E-03 2.4162982E-04 6.5253494E-14 1 -1.180058 4.517548 4.129065 1.292174 0.8199469 4.9999999E-06 7662425. 0.6389125 -2.1305513E-03 2.3861929E-04 6.5253494E-14 1 -0.8277293 4.516370 4.129196 1.842072 1.172278 4.9999999E-06 7662425. 0.6431691 -2.1652121E-03 2.3706595E-04 6.5253494E-14 .... and so on... Also is there a way to extract certain particle variables out and output them into a file itself? Thanks! |

Hello,
I am conducting a steady state analysis of pump and I am looking to track the particles (more or less same example as butterfly valve with erosion tutorial). The problem is I am only generating blank particle file. The .trk files are simply empty. Also, the .trk file is only created for 1 particle with pT1.trk file. How do I keep track of all the 20 particles? Do anyone has a way around it? or, helpful links? While I am at it, would it be possible to generate impact velocity data of those particles from CFX? |
