Can you provide a patch which resolves this problem? |
|
|
I'm sorry, but I have little experience with C++ |
|

foamMonitor is a script, not C++, it is in the bin directory: #!/bin/sh #------------------------------------------------------------------------------ # ========= | # \\ / F ield | OpenFOAM: The Open Source CFD Toolbox # \\ / O peration | Website: https://openfoam.org # \\ / A nd | Copyright (C) 2015-2019 OpenFOAM Foundation # \\/ M anipulation | #------------------------------------------------------------------------------ # License # This file is part of OpenFOAM. # # OpenFOAM is free software: you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by # the Free Software Foundation, either version 3 of the License, or # (at your option) any later version. # # OpenFOAM is distributed in the hope that it will be useful, but WITHOUT # ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or # FITNESS FOR A PARTICULAR PURPOSE.

I'll take a look at it |

The problem is caused by having more spaces between "#" and "Time" as you see in file postProcessing/probes/0/p # Probe 0 (1e-06 0 0.01) # Probe 1 (0.21 -0.20999 0.01) # Probe 2 (0.21 0.20999 0.01) # Probe 3 (0.21 0 0.01) # Probe 0 1 2 3 # Time The cut command in the foamMonitor script (row 181 and 182) causes this problem as described in the following link https://stackoverflow.com/questions/816820/use-space-as-a-delimiter-with-cut-command The following modification in the foamMonitor script would resolve this problem: -181: xlabel=$(echo "$keys" | cut -d " " -f2) +181: xlabel=$(echo "$keys" | tr -s " " | cut -d " " -f2) -182: keys=$(echo "$keys" | cut -d " " -f3-) +182: keys=$(echo "$keys" | tr -s " " | cut -d " " -f3-) |
|
|
This is the correct postProcessing file: # Probe 0 (1e-06 0 0.01) # Probe 1 (0.21 -0.20999 0.01) # Probe 2 (0.21 0.20999 0.01) # Probe 3 (0.21 0 0.01) # Probe 0 1 2 3 # Time ^^^^ |

When copying the spaces will be removed. Therefore the file is attached to see the right positions. p (1,314 bytes)
# Probe 0 (1e-06 0 0.01)
# Probe 1 (0.21 -0.20999 0.01)
# Probe 2 (0.21 0.20999 0.01)
# Probe 3 (0.21 0 0.01)
# Probe 0 1 2 3

The problem isn't foamMonitor, the problem is the output of probes. All other data output of this kind that I can find (residuals, forces, interfaceHeight) has the following format: # Arbitrary number of lines of header # ... # ... # ... # x-name y0-name y1-name y2-name 1 2 3 4 5 6 7 8 Whether as probes has this: # Arbitrary number of lines of header # ... # ... # ... # y-name y0-subName y1-subName y2-subName # x-name 1 2 3 4 5 6 7 8 Probes predates everything else, so the difference is probably just historic. FoamMonitor can't be expected to be compatible with a variety of inconsistent input formats. Probes needs fixing so it matches the formatting of the other functions. |
