Dear all,
I am conducting a quasi 3D simulation, being the z-axis the homogeneous 
direction, with an homogeneous length equal to 0.1 (LZ=0.1) and up to 3 
Fourier modes (HomModesZ = 4).
I am interested on placing some history points along the homogeneous 
direction, however I am facing several issues which I would like to clarify.
- First of all, I have made several tests and it seems that it is not 
possible to parametrize the points coordinates. I mean, the coordinates 
do not accept parameters defined on the parameters XML element. The 
following example does not provide any output result:
<PARAM NAME="Points">
         0.0 LZ 0.0
</PARAM>
Is there any way to parametrize the coordinates? since it will be very 
beneficial.
- I would like to place probes at LZ/4, LZ/2 and 3*LZ/4, thus I defined 
the HistoryPoints filter as follows:
<PARAM NAME="Points">
         0.0 0.0 0.025
         0.0 0.0 0.05
         0.0 0.0 0.075
</PARAM>
However, I obtain the following 'error' message: Reseting History point 
from z = 0.075 to z = 0.05. As not Fourier interpolation is required, 
why do I get this error?
- At the FilterHistoryPoints.cpp file I see that it is possible to 
specify the plane on which to evaluate the history point by using the 
"OutputPlane" tag. Since I could not find any example, I would like to 
know how to use this tag, more in precise, how to define the 
z-coordinate of the points along with the output plane. Is the following 
example correct?
<FILTER TYPE="HistoryPoints">
<PARAM NAME="OutputFile">TimeValues</PARAM>
<PARAM NAME="OutputFrequency">10</PARAM>
<PARAM NAME="OutputPlane">0,1,2,3</PARAM>
<PARAM NAME="Points">
     1 0.5 0
     1 0.5 0
     1 0.5 0
     1 0.5 0
</PARAM>
</FILTER>
I expect to obtain the measurements at the coordinates 
(1,0.5,0),(1,0.5,0.025),(1,0.5,0.5),(1,0.5,0.075).
- Also at the FilterHistoryPoints.cpp file I have seen that there is 
another tag, called "WaveSpace". If I implement it, will I obtain the 
Fourier coefficients on these points? It is somehow confusing to me, so 
I please you to bring some light into it, and how to use this field.
I am using nektar 4.3.3 version and running in parallel with 8 cores. 
Let me know if you require any other information.
With best regards,
Guillermo
