Off fault receivers¶
Ascii receivers are enabled using the namelist output. Here is a commented example:
&Output pickdt = 0.01 ! Pickpoint Sampling pickDtType = 1 ! Pickpoint Type nRecordPoints = 22 ! number of Record points which are read from file RFileName = 'receivers.dat' ! Record Points in extra file iOutputMask = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 /
If pickDtType = 2, the output is generated every N time steps, where N is set by pickdt. If pickDtType = 1, output is generated every pickdt second.
receivers.dat is an ASCII file describing the coordinates of the receivers in the form:
x1 y1 z1 x2 y2 z2 (...) xn yn zn
iOutputMask acts as well on the wavefield output.
Placing free-surface receivers¶
Placing receivers on the free-surface requires special care when a realistic topography is used. The procedure to move receivers exactly to the surface is described here.
