trace_direction

ptrace.trace_direction(p0: str) → int

Sets the integration direction for a particle trace - forward in time, backward in time, or both.

By setting this option appropriately, one can see where a particle will go if released from the emitter location (the + direction), or one can see the path that a particle took to get to the emitter location (the - direction).

Args:

p0:

‘direction’

• +/-

Examples:

#
# Selecting the trace(s)
#
ensight.part.select_begin(7,8)
#
# Modifying attributes for the two selected trace parts
# (trace_direction is modified in here)
#
ensight.part.modify_begin()
ensight.ptrace.total_time(2.0000e+02)
ensight.ptrace.trace_direction("+/-")
#
# Updates the traces with the modified attributes
#
ensight.part.modify_end()

Returns:

zero on success, non-zero on error
