3D Slice File Visualisation in Smokeview

[Kate Mccombe]

Hi Everyone,

I'm new to FDS and having some trouble with the 3D slice function in Smokeview. I've asked for a 3D slice file for a vent releases a toxic gas, but what I see in smokeview is a visual representation of a 2D plane of the vent (not the volume I specified). Is this what it's meant to output? This is the relevant part of the code:

&SURF ID='SUPPLY', SPEC_ID='FUMES', MASS_FLUX_TOTAL=5, RAMP_V='SUPPLY RAMP', TAU_V=5 /

&RAMP ID='SUPPLY RAMP', T=0., F=0.0/

&RAMP ID='SUPPLY RAMP', T=1., F=1.0/

&RAMP ID='SUPPLY RAMP', T=3., F=1.0/

&RAMP ID='SUPPLY RAMP', T=4., F=0.0/

&RAMP ID='SUPPLY RAMP', T=60., F=0.0/

&VENT XB=-1.046, -1.046, 0.0, 0.2, 1.0, 1.2, SURF_ID='SUPPLY', COLOR='RED' /

&PLOT3D_SPEC_ID = 'FUMES'

&DUMP PLOT3D_QUANTITY='VOLUME FRACTION',PLOT3D_SPEC_ID = 'FUMES', DT_PL3D = 1 /

&DUMP DT_SL3D = 1/

&SLCF XB=-2.0, -1.046, 0.0, 0.2, 1.0, 1.2, QUANTITY='VELOCITY', VECTOR=.TRUE./

Thank-you!

with a 3d slice file you will only see one 2D slice at a time.  you can use the x, y, z keys to show hide slices along the x, y, z axes and the arrow and page up/down keys to move the slices.

Ahh, thank-you both!
