- \b type - One of FUEL or OXIDIZER. This is required.
- \b radius - Equivalent radius of tank for modeling slosh, defaults to inches.
+- \b grain_config type - One of CYLINDRICAL or ENDBURNING.
+- \b length - length of tank for modeling solid fuel propellant grain, defaults to inches.
- \b capacity - Capacity, defaults to pounds.
- \b contents - Initial contents, defaults to pounds.
- \b temperature - Initial temperature, defaults to degrees Fahrenheit.
- \b standpipe - Minimum contents to which tank can dump, defaults to pounds.
+- \b priority - Establishes feed sequence of tank. "1" is the highest priority.
+- \b density - Density of liquid tank contents.
location:
- \b x - Location of tank on aircraft's x-axis, defaults to inches.
- \b y - 0.0 (both full and drained CG locations)
- \b z - 0.0 (both full and drained CG locations)
- \b radius - 0.0
-- \b capacity - 0.0
+- \b capacity - 0.00001 (tank capacity must not be zero)
- \b contents - 0.0
-- \b temperature - -9999.0
-- \b standpipe - 0.0
+- \b temperature - -9999.0 (flag which indicates no temperature is set)
