xconv segfault

Description

Hi All

The following (xconv 1.93)

xconv /nerc/n02/n02/pmonerie/work/xnspd/dataw/xnspda.ph19810916 /nerc/n02/n02/pmonerie/work/xnspd/dataw/xnspda.ph19811116

results in a Segmentation fault

but
xconv /nerc/n02/n02/pmonerie/work/xnspd/dataw/xnspda.pi19810916 /nerc/n02/n02/pmonerie/work/xnspd/dataw/xnspda.pi19811116

does not.

It's not obvious to me why the *.ph* files do this - any ideas?

the *.ph*16 fields have

0 : 39 42 1 360 Net short wave radiation flux
1 : 39 42 1 360 Total downward surface solar flux over sea-ice.
2 : 40 42 1 360 Wind speed
3 : 39 42 1 360 Maximum wind gust at 10m
4 : 192 145 1 195 Wind speed
5 : 192 144 1 120 CH - bulk transfer coefficient of heat
6 : 192 144 1 75 Maximum wind gust at 10m
7 : 192 144 1 16 Temperature T
8 : 192 144 1 15 Relative humidity
9 : 192 144 1 15 Total precipitation rate

the *.pi* fields have

0 : 39 42 1 360 Net short wave radiation flux
1 : 39 42 1 360 Total downward surface solar flux over sea-ice.
2 : 40 42 1 360 Wind speed
3 : 192 144 1 16 Temperature T
4 : 192 144 1 15 Relative humidity
5 : 192 144 1 15 Total precipitation rate

Having said that:

xconv /nerc/n02/n02/pmonerie/work/xnspd/dataw/xnspda.pi19811016 /nerc/n02/n02/pmonerie/work/xnspd/dataw/xnspda.pi19811001 /nerc/n02/n02/pmonerie/work/xnspd/dataw/xnspda.pi19810916

also segfaults. Is it the presence of mixed horizontal grids that is causing the problem?
Any way around this?

Hi Dan,

I confirm it seg faults for me too. Also xconv 1.92 does the same. Thinking …

Xconv will take the 2D fields in a fieldsfile/pp file and try to make a 4D (xyzt) field, sometimes it has problems doing this when the file has the same field on different levels at different times.
