Smokeview dies when loading a SLCF and then a BNDF.

[mcgratta]

Run this case

&HEAD CHID='ray_effect_example', TITLE='Demonstrate ray effect'/

&MESH XB=0.0,1.0,0.0,1.0,0.0,1.0, IJK=100,100,100 /

      TIME_STEP_INCREMENT = 1
      ANGLE_INCREMENT = 1 /

&TIME T_END=0.1, DT = 0.1  /

&SURF ID='HOT'  TMP_FRONT=100, TAU_T=0., EMISSIVITY=1., HEAT_TRANSFER_COEFFICIENT=0., COLOR='RED'  /
&SURF ID='COLD' TMP_FRONT=20., TAU_T=0., EMISSIVITY=1., HEAT_TRANSFER_COEFFICIENT=0., COLOR='BLUE' /

&SLCF PBY=0.5, QUANTITY='INTEGRATED INTENSITY' /

&BNDF QUANTITY='GAUGE HEAT FLUX', CELL_CENTERED=.TRUE. /

&TAIL /

and then in Smokeview load the slice file and then the boundary file. I have the Windows Sept 11 build, and this causes Smokeview to shut down.

Glenn,
I confirm the fault with this build:

this is the definition of insanity. your case crashed for me too but not every time. there are only 2 time steps in the data files. could you try running the case for longer say 1.0 s and see if it still crashes.

[gforney]

ps: reason for asking want to know if smokeview is having trouble dealing with a small number of time steps in the data files.

[rmcdermo]

If I run the case to 1 s, then it works.

You can find the case in:

At the risk of barely providing any additional information, I have had problems at times this year with consistently loading boundary files. Smokeview would crash during the load. These are very large boundary files, so definitely not the < 1 s problem. There are 23 meshes.

I never posted an issue on this because I could not consistently reproduce it, although I tried a number of times to narrow it down. (It's also a large problem that does not lend itself to easy simplification.) Based upon my analysis, I'm pretty sure that it had nothing to do with CPU, memory, disk space, etc. I would then restart Smokeview and load the boundary file and it would work.

I believe I was running SMV 6.4.4 most of the time (although I think I did some periodic upgrades), so I'm not sure if the problem is still there and that's why I'm just adding to this issue. I'm running 6.5.5 now, so I'll let you know if it reappears.

Thank you.

I fixed a pointer that is NULL sometimes. try smokeview here

[sbenkorichi]

Running the example case shared by Kevin with smv in the link, it works under Linux. No shutdown noticed.

[gforney]

is this still a problem?
here is the latest test smokeview

[mcgratta]

This issue is resolved. I just double-checked.
